But what if you only have a standard cellphone with a lousy Web browser — or even the best Web-browsing phone, but it lacks a fast data connection? What if you’re speeding down the road in a car, where typing is dangerous?

Now, there’s a way to get your questions answered despite those hurdles. It’s a free cellphone service that lets you ask any question answerable via a Web search, using any cellphone, by simply making a voice call. It’s called ChaCha, and I’ve been testing it out.

To use ChaCha, you just dial 800-2chacha (800-224-2242) and state your question. In a few minutes, you’ll get an answer via text message. In one test, I asked ChaCha who was the winning pitcher in the previous night’s Red Sox victory against the Yankees. In a few minutes, I received a text message with the correct answer: Daisuke Matsuzaka.

ChaCha requires no registration and works on any cellphone carrier. It needs no special codes or key words. You just state your question as if you were asking a friend. If you prefer to type your question, you can text it to “ChaCha,” or 242242. Though ChaCha itself charges no fees, your phone carrier may charge for the minutes you use, or for the text messages.

The service works by routing your questions to one of 10,000 hired “guides” — students, stay-at-home parents, retirees and others — who look up the questions on the Web and reply. They get paid 20 cents per answer.

Naturally, these guides vary as to their speed and accuracy. If you don’t like the answers they give you, or you want related information, you can call back or reply to the text message with a follow-up question. For instance, after learning which pitcher had won for Boston, I asked who lost the game for New York. I was quickly informed it was Phil Hughes.

Overall, I liked ChaCha. In most cases, I received fast, accurate, useful answers. But it has two weaknesses. One is that the low-paid, part-time guides can provide inconsistent service. When I asked for the best Mexican restaurant in D.C., for example, ChaCha came up with a choice that few locals would cite.

The other is that, unlike many other cellphone information services, ChaCha doesn’t automatically know your location. So, unless you include a location in your query, it’s clueless about questions such as “Where’s the nearest drugstore?”

ChaCha is hardly the only information service for cellphones. Google offers a text-message service where you can ask questions on a wide variety of topics, and a voice-based service that locates businesses near your location. Microsoft’s TellMe subsidiary just introduced a voice-based service that answers location-specific questions about businesses, weather, traffic and movies, and displays the answers on the screens of BlackBerrys.

But these competitors are more limited than ChaCha in key respects. Google’s broader mobile-search service, Google SMS, requires that questions be sent via text message using special key words. Its voice service, Goog411, finds only local businesses. TellMe’s new service is limited to location-based information and works only on certain phones.

I tested ChaCha using three very different phones: a cheap, bare-bones Samsung flip phone from Sprint; a midrange Motorola Razr from Verizon; and an Apple iPhone running on AT&T. I asked questions via voice and text from various locations, including my car, where I used a hands-free microphone.

I asked about sports, TV shows, journalism, history, weather, nutrition, demographics and shopping. ChaCha handled most of these inquiries correctly and was able to fix most of its errors after I asked follow-up questions. For each question, it sends two text messages: one restating your query and saying it’s working on it, and the second containing the answer.

Each ChaCha answer is accompanied by a Web link. If your phone has a decent browser, you can go to that link to learn who the guide was, and what his or her Web-site source was.

ChaCha gave me the weekend weather forecast in Boston, the date of death of Abigail Adams and the cast of the TV show “Brothers & Sisters.” It provided Peyton Manning’s salary and the sodium content of a McDonald’s quarter pounder. Its most impressive performance came when it correctly answered an obscure historical question: “When was the Gaspee burned?” The Gaspee was a British tax-collection ship burned in Rhode Island in 1772 in what is often considered the first act of war of the American Revolution.

The company is working on adding automated location knowledge, at least on certain carriers and phones. For now, you can tell it your location by sending a special command via text message. But even without the location features, ChaCha is a fun and useful service.

ChaCha, a mobile-phone search service, is incompatible with several small U.S. cellphone carriers. This column incorrectly said that the service works on any cellphone carrier, based on incorrect information supplied by the company.

Dell has been having a tough time lately. Once the widely admired leader among PC makers, it has lost its sales crown to Hewlett-Packard and has seen its once-legendary customer satisfaction plunge.

In an attempt to jazz up its image, the stodgy behemoth recently introduced a line of thin, sleek, colorful consumer notebooks, the XPS M1330 series, but has been unable to build the machines on schedule.

Now, Dell is making another interesting move to better address the market. It has introduced a new sub-brand of computers intended for perhaps the most poorly served segment of computer buyers: really small businesses with 25 employees or less that have no full-time IT departments.

The new Dell line for these very small businesses is called Vostro. It fits into a new Dell brand lineup. All Dell’s consumer models, both laptop and desktop, are called Inspirons, a name formerly reserved only for laptops. Big business models are still called Latitude, Optiplex or Precison. High-performance consumer models are called XPS.

I’ve been testing a midrange Vostro model, a laptop with a 15.4-inch screen called the Vostro 1500. It’s a bulky, plain machine with nothing built in that Dell doesn’t already offer on consumer models, and some omissions that could make for extra setup work for small businesses. But it is fairly affordable and, to Dell’s credit, it comes without the useless trial software Dell and others cram onto consumer PCs.

Judged by its hardware and software, the Vostro 1500 is mostly a branding-and-marketing ploy at the moment. Dell concedes the new line is “just a first step” in what it swears will be a major initiative to serve very small businesses.

The only real small-business innovation lies outside the product itself: a dedicated phone support staff that Dell says has been trained specifically to serve these small companies. But unless you pay extra, you’ll still be dealing with support people based outside the U.S. — in Canada and in the Philippines, far from Dell’s Texas headquarters. Only time will tell if these folks can really provide better-than-usual service.

The Vostro 1500 starts at just $549, but that base model has very little memory and a small hard disk. The configuration Dell lent me for testing, with a decent two gigabytes of memory and a 160-gigabyte hard disk, plus an extra-large battery and a built-in Sprint cellular modem, costs $1,701. Dell says it’s available today at a promotional price of $1,327. The optional Sprint service requires a monthly fee, usually $60.

There are three other Vostro laptop models, including a very basic design called the Vostro 1000 that starts at just $449. Dell also offers Vostro desktops.

The Vostro 1500 I tested came with Windows XP instead of Windows Vista. Most Vostro models can be ordered with XP, which may be a welcome choice for small businesses that don’t want to wrestle with the continuing lack of compatible software and hardware for Vista.

Dell touts several features that it builds into the Vostro machines. One is a network setup program called Network Assistant. Another is PC Tuneup, which is maintenance software. A third is an online backup service that stores up to 10 gigabytes of data.

These are all useful, but none is new or tailored to small businesses. All were already available for Dell’s consumer models, albeit for small fees. Even the choice of Windows XP and the option to order a computer without any trial software have been available on some Dell consumer models.

Still, there were some surprising omissions on the Vostro that I tested. There was no security software, not even the usual 90-day subscription. Dell notes that you can opt to get the 90-day subscription free of charge and buy a 15-month security package for $79. It figures that many small businesses might already have access to security software. But because this is a necessity, installing it after the fact could be a hassle.

The Vostros with XP, like my test unit, also lack a modern, secure Web browser. They come with the old, insecure Internet Explorer 6.0 instead of Mozilla’s Firefox or Microsoft’s much safer Internet Explorer 7.0. A small business buying a Vostro with XP would have to immediately replace the browser.

And the Vostro doesn’t come bundled with any small-business software.

In my tests, the Vostro 1500 performed just fine, running quickly and easily connecting to my Wi-Fi network. But it’s a heavy, thick box that would be a burden for travelers. My configuration tipped the scales at seven pounds.

Yet, the battery life was only fair for such a bulky laptop, even with the extra-large battery. In my harsh battery test, where I turn off all power-saving software and play a loop of music, the Vostro 1500 lasted three hours and 36 minutes, meaning you’d likely get five hours, at most, in normal use. The standard battery would get you about a third less power.

Overall, the Vostro 1500 is just an OK laptop, which isn’t different enough from consumer models to really earn the small-business designation it claims.

Corrections & Amplifications:

Dell Inc. has introduced a computer line named Vostro for users at very small businesses. An earlier version of a headline on this column incorrectly said the line was named Vostra.

In fact, this category is getting so crowded that it’s hard to follow all of the contenders. T-Mobile and Sprint, for example, have just announced very similar smart phones running Microsoft’s latest Windows Mobile software. Both feature horizontal keyboards that slide out from beneath the screen. The T-Mobile Wing costs $299 after various rebates, while the Sprint Mogul, which runs on a faster network, costs $399.

But I’ve been testing two other new smart phones that I find especially interesting. One is the latest attempt by BlackBerry maker Research In Motion to appeal to consumers. The other is a high-resolution camera phone by Nokia, which costs more than even the iPhone.

The new BlackBerry Curve 8300, sold by AT&T, is sort of a cross between the maker’s low-end consumer-oriented Pearl and its larger, more traditional models like the 8800 series. It costs $199 after rebate, with a two-year contract.

Unlike the Pearl, which manages its slender size by sporting only a squished keyboard where two letters must share each key, the Curve has a full, if slightly compressed, keyboard. I found it no problem to use accurately. It does, however, use the Pearl-like trackball instead of the famous BlackBerry side-mounted wheel.

To accommodate the keyboard and a wider screen, the Curve is wider and a bit thicker than the Pearl, and has more of the traditional BlackBerry look. And it’s over 20% heavier. But it’s narrower, shorter and lighter than the 8800, though a bit thicker.

The silver-colored Curve doesn’t boast any technological breakthroughs. It’s mostly an attempt to bring the BlackBerry’s email capabilities to a model that doesn’t compromise the keyboard the way the Pearl did. It has all the traditional BlackBerry features, plus a two-megapixel camera, a slot for a memory card, and the ability to play music and videos.

In my tests, I had no trouble at all sending and receiving email on the Curve, taking or displaying pictures, or playing music. I was able to move over some songs and pictures from my own computer, and they displayed and played as promised. Voice quality was fine, and phone talk time is about four hours — reasonable but not outstanding.

In a welcome move, the Curve has a standard headphone jack, capable of playing music in stereo and handling phone calls. It also includes Bluetooth for wireless headsets and use in cars, but it doesn’t have Wi-Fi wireless networking. It also runs on AT&T’s relatively slow EDGE network instead of the carrier’s faster data network. And the Web browser is mediocre.

The Nokia N95 lacks a full keyboard, physical or virtual and its email is primitive, but that’s not its main purpose. This device is the best combination of a camera and a phone I’ve ever tested, and includes a long list of other media features.

The camera boasts five megapixel resolution, highly unusual for a phone, and it takes marvelous photos. When I transferred my shots to my computer, they were large, sharp and vivid, just as if they’d come from a standard camera. The camera has Carl Zeiss optics, autofocus, multiple flash settings and various scene settings. It also has a burst mode capable of taking six shots in rapid sequence.

But getting such a good camera in a phone will set you back a whopping $749. And you can’t buy it through any phone carrier, only from Nokia’s Web site (nseries.com) or from various electronics stores. You have to buy a phone plan separately.

Nokia’s N95, left, and BlackBerry’s Curve 8300

Like the Curve, the N95 has good voice quality, but runs on the slow EDGE network, though a future version could support faster networks. Unlike the BlackBerry, the current N95 also can use Wi-Fi networks. Battery life is only fair: 3.5 hours of talk time. While Nokia touts the phone’s Web browser, I found it to be unimpressive. But the phone includes GPS mapping, with optional navigation. It also accepts memory cards for storage.

Physically, the N95 is small, but chunky; on one side, it looks like a plum-colored camera. If you slide its screen in one direction, the keypad is revealed. Sliding it the opposite way reveals standard controls for playing music and video clips. I was able to move pictures and songs from my computer, but the songs failed to display album covers when played.

For $749, you could buy the Curve and a very nice digital camera. But the N95 is for photo enthusiasts who want an all-in-one device. The Curve is a more mainstream smart phone that aims for a balance of features at a low price.

The latest, and most unusual, of these music phones has just been announced by Sprint. It’s a Samsung model called the UpStage. The UpStage costs just $149, less than a third of the iPhone’s planned $499 price, and it will go on sale early next month.

Samsung has shown real creativity in solving the problem of cramming a decent music player and phone into one small gadget. The slim UpStage has been designed with two distinct faces. On one side, it has a phone keypad and a small screen, for making voice calls and tapping out text messages. But if you turn it over, you see a larger screen and navigation controls, mainly for playing music, but also for other tasks, such as viewing online data.

Sprint’s UpStage music cellphone by Samsung.

At the same time, Sprint is slashing the price of songs sold on its proprietary music service from an outrageous $2.49 each to just 99 cents. That isn’t quite as cheap as it seems, because you have to pay $15 a month for the privilege of buying the 99-cent songs. But it’s still a positive step for consumers.

I’ve been testing the UpStage and found that its two-sided design works pretty well. It’s a better music phone, in my opinion, than Verizon’s Chocolate model, built by Samsung’s Korean rival, LG.

But the UpStage has too many weaknesses and compromises for me to recommend it. It has lousy battery life, both as a phone and as a music player, a limitation Sprint and Samsung have tried to offset with a free add-on that makes the phone too bulky. And it comes with so little memory that, out of the box, it can hold only around 20 average songs. Adding more capability costs extra, thus lessening the price advantage. There are other downsides as well.

I tested the UpStage primarily as a music player, because that’s its claim to fame. I compared it with the base-model iPod Nano, which also costs $149, although of course it doesn’t include a phone.

I did try out the basic phone stuff, like making calls, all of which seemed OK, though the screen on the phone side of the device is very small, a sort of throwback to early cellphones. Sound quality, reception and the keypad all were fine. The built-in 1.3 megapixel camera is standard for phones these days.

Only one of the phone’s two screens can be used at any one time, and you have to press a “flip” button on the side to switch. This worked well, but was kind of a pain when I was trying to use the keypad to type in text, like a Web password or the name of a new song playlist, on the music side of the phone. I had to flip to the side with the keypad and then flip back.

I loaded in about 20 songs and the UpStage played them back pretty well, displaying all the correct song information and album art. I also loaded in some photos, which also displayed fine, though the phone can handle only small picture files. I purchased a song from Sprint’s music service, and that downloaded and played well.

The only problems were that the album covers and photos looked grainy, because even the larger screen has pretty low resolution. And occasionally, the start of a song was clipped. The iPod Nano exhibits neither of these problems.

Out of the box, the UpStage comes with only a tiny memory card, which can hold only around 20 standard MP3 files. The iPod Nano can hold 500 of those files. To get the same capacity on the UpStage, you have to buy a larger, $40 memory card.

Though the UpStage is bigger than the iPod Nano, it has far worse battery life — just 2.5 hours of talk time for the phone and seven hours of music playback time, compared with up to 24 hours of music playback time for the Nano. To compensate, Sprint is throwing in a “battery wallet,” a case with an additional battery built in. This brings the talk time to 6.3 hours and music playback time to around 17 hours. But it makes the phone twice as thick.

There are two other problems with the UpStage. First, synchronizing its music with songs stored on a PC requires you to install and use Sprint music software. It doesn’t work with Windows Media Player or the Windows version of Apple iTunes, which most music lovers already own. (You also can manually drag and drop songs onto the phone’s memory card.)

Second, the navigation pad on the music side of the phone can be confusing. It works by touch controls; you have to use just the right pressure and slide your finger just the right distance along its sides to get it to work right. It’s too complicated.

Samsung and Sprint deserve credit for a good try with the UpStage. But it doesn’t quite cut it.

The slender Motorola Q, despite software that is markedly inferior to that of the Treo 700p, is wooing some users because it is much slimmer and now can be had for just $99, versus $299 for the Treo. The Nokia E62 is about the size of the Q and also costs just $99 these days. The tiny BlackBerry Pearl is just $199. And Samsung has introduced the skinny BlackJack for $199, too.

So, this month, Palm is striking back with a lighter, thinner, cheaper model of its own, the Treo 680, which is being offered by Cingular Wireless at $199.

Meanwhile, T-Mobile has introduced a new slim, light competitor called the Dash. It has built-in Wi-Fi wireless networking to supplement the slower cellphone data network. And it costs just $149.

I’ve been testing the new Treo and the Dash. Both are OK, but neither is as good as it could be. The new Treo still has great software, but it makes some compromises and still fails to match the new competitors in slimness, lightness or price. The Dash has very nice hardware, but is hampered by lousy software.

The Treo 680 is shorter than the Treo 700, because it doesn’t have the 700’s protruding antenna. It’s about 11% thinner and 14% lighter. But it’s still much larger than the new class of Q-type competitors. The Dash is slightly wider than the new Treo and about the same length. But it’s much thinner and lighter. The Dash feels great in your hand because it has rubberized paint.

This new Treo works just like the 700p. It uses the same Palm operating-system software, which is much easier and faster than the Windows Mobile software used by the Dash and the Q. As I have noted in the past, simple operations like deleting an email or displaying your calendar are usually one-click processes on the Palm OS devices, while they often take two or more clicks, or involve opening menus, on the Windows devices.

Also, the Treo 680, like the costlier 700p, comes with better functionality for handling Microsoft Office documents than the Dash does, even though the latter uses Microsoft software. The 680 has the same large, high-resolution screen as the 700p. By contrast, the screen on the Dash, while bright and vivid, is lower resolution.

But the new 680 is less capable than the 700 series Treos. First, it runs on a much slower cellphone network, called EDGE. This EDGE technology isn’t broadband speed, and is only about one-seventh as fast as the networks from Verizon Wireless and Sprint that the Treo 700 uses. Cingular does have a new network with speeds comparable to Verizon’s and Sprint’s, but the Treo 680 can’t take advantage of it.

Second, the Treo 680 is a big step backward in terms of its camera. The camera’s resolution is only about a third of a megapixel, while the camera on the Treo 700 — and the Dash — is 1.3 megapixels. Finally, the stylus on the Treo 680 is cheap and just plain awful. It actually bends when you use it.

The Dash is also stuck on the slow EDGE network technology because that’s the best data network T-Mobile currently offers. It makes up for it with built-in Wi-Fi, which is much faster than EDGE, and potentially much faster than the Verizon and Sprint cellphone data networks.

In my tests, I was able to use the Dash for email and Web browsing via Wi-Fi in my office, my home and a couple of coffee shops. The Wi-Fi setup and connection process was fairly easy, and T-Mobile has added software to the Dash that guides you through setting up access at Wi-Fi hot spots it operates in airports, Starbucks shops and other locations.

In fact, T-Mobile offers a data plan for $30 a month that includes both cellphone Internet service and access to its Wi-Fi hot spots. This is on top of the cost of a voice plan.

There are some downsides. The Dash doesn’t automatically switch on Wi-Fi. You have to do it manually. And, in my tests, it was much slower using Wi-Fi than a laptop was. For instance, in my home, on my very fast Wi-Fi connection, the Dash got just under one megabit per second, while a Mac laptop inches away got over 14 mbps. On a slower network in my office, the Dash got around half a megabit per second, while a computer inches away got 1.3 mbps.

I also found the keyboard on the Dash to be more cramped and harder to use than the one on the Treo. And the touch strip it uses to control volume didn’t work well.

If you have always wanted a Treo, but couldn’t handle the price tag, the 680 may be for you. Just be prepared for its slower speed and inferior camera. If you yearn for Wi-Fi in a slender smart phone, and can put up with a clumsy software interface, go with the Dash.

But that image will change radically next week when the BlackBerry’s maker, Research in Motion, introduces a sleek but powerful model called simply the Pearl. It’s not only the smallest BlackBerry ever made. It’s also the smallest smart phone from any maker with a keyboard for typing emails and other text.

All shiny black and silver, the slender Pearl looks more like a fashion phone than a keyboard-equipped smart phone. It is shorter, narrower and lighter than the much-admired Motorola Q, though a bit thicker. And, like the Q, the Pearl, which is being launched next Tuesday by T-Mobile, costs $199 with a two-year contract. The Pearl is squarely aimed at consumers who need powerful email capabilities, but also want style and bells and whistles.

When it comes to email, the Pearl is a true BlackBerry. The email interface is essentially the same as on larger BlackBerrys. It can be used with a traditional corporate BlackBerry email system, and, for consumers, it works with the BlackBerry Internet Service offered by T-Mobile.

Still, for hard-core BlackBerry addicts, the Pearl is a shocking departure. The iconic side scroll wheel has been replaced by a tiny, light-up trackball beneath the large, bright color screen. It’s the first BlackBerry with a camera, the first with a memory card slot (though no card is included) and the first to play songs and videos.

And then there’s the keyboard, where the slim new design has required a major compromise. As on the older and bulkier BlackBerry 7100 series, the full keyboard has been replaced by a smaller version that squeezes two letters onto most keys. To avoid repetition and error, the Pearl uses smart software called SureType that has the uncanny ability to guess the word you meant to type in almost all cases. But it doesn’t work if you’re entering a new Web address or a person’s name that the phone hasn’t memorized.

To find out if RIM can actually be cool, I’ve been toting around a Pearl, testing all its functions. In general, I like it, and can recommend it to anyone who wants real BlackBerry email capabilities in a great-looking multimedia phone. Voice quality was excellent and the interface for making phone calls, once a big problem on BlackBerrys, is now decent. There’s even a Treo-like universal silencer button, and the speaker phone function turns on and off with a single key press.

Setting up an email account with the BlackBerry Internet Service is easily done, either on the phone or via a T-Mobile Web page. This service replaces a corporate email server with a Web-based email system that pushes messages to the phone from an existing email account or from a new one. T-Mobile plans to charge $19.99 a month for unlimited email and Web browsing on top of the price of an existing voice plan.

The Pearl pushed my normal email to the phone perfectly, and, in that respect, it acted just like every other BlackBerry I’ve used. Because of the different keyboard, some of the keyboard shortcuts for navigating in email and other applications differ from those on older models. If you change a couple of settings, you can delete an email with one click, and whole batches of emails can be deleted with two clicks.

Popular email attachment types, including Microsoft Word and Excel files, can be opened and read, but not edited. I was able to easily synchronize calendar and contact entries with Microsoft Outlook on a Windows PC, and to easily transfer songs, pictures and videos to the Pearl using RIM’s desktop software.

The Pearl’s music software correctly read the artist, album and song information on every track I loaded into the phone, and even displayed the album covers. The speaker on the Pearl sounds good, and music sounds even better with stereo headphones.

Photos also displayed well, and the Pearl can zoom in on them or show them as slideshows. Any song can be turned into your ring tone, and any picture can be used as your desktop wallpaper.

The Pearl really shone when playing video. Unfortunately, it accepts only a limited number of video file types, and even many of those I tested didn’t work. Some videos sucked up so much of the phone’s power that other functions, even pausing the playback, were very slow.

The Web browser is OK, but it’s hampered by what I consider the biggest drawback to the Pearl: the network on which it runs. T-Mobile uses a network technology called EDGE, which is much, much slower than the fastest networks offered by Verizon, Sprint and Cingular.

There’s another reason I’m not trading my Palm Treo 700p for a Pearl: the user interface. While RIM has jazzed up the hardware and feature set, there’s still way too much multiple clicking and menu opening for my taste.

But the Pearl is a beautiful piece of work, a very nice combination of hard-core email capability and fun features.

The Finnish cellphone giant is introducing a phone called the E62 that resembles, and is aimed at, the Palm Treo, the latest BlackBerry phones from Research In Motion and the Motorola Q.

Nokia’s E62

Like those other smart phones, the E62 has a full keyboard and is actually a little computer that is meant to be a serious email device as well as a phone. Like the Q and the Treo, it can play music and videos, surf the Web, and display photos.

Unlike the Treo and the Q, however, the Nokia E62 can run a service licensed by RIM that allows it to behave like a BlackBerry. It can send and receive email using either a corporate BlackBerry server or a consumer BlackBerry service offered by a cellphone carrier.

I’ve been testing the E62 and I like it. It’s fairly utilitarian-looking and won’t likely become an object of desire like the Q and the Treo. But it gets the job done and may well be the best bargain in its category.

In the past, Nokia has relied on a smart-phone design that was a thick, long device that flipped open to reveal a wide, horizontally aligned keyboard and screen. That design sold OK in Europe but flopped in the U.S. Now, with the E62, Nokia is adopting the American-type design pioneered by the BlackBerry and used by the Treo and the Q.

Nokia is being coy about the timing, pricing and wireless carrier for the E62. But I expect it to be available late next month from Cingular Wireless. And I expect it to cost even less than the Q, which at $199 is the least expensive product in this group. The latest Treo models, the 700p and 700w, are being sold by Verizon Wireless for $299 right now, after rebates.

The E62 works on the so-called GSM cellphone standard that’s universal in Europe, and used by Cingular and T-Mobile in the U.S. This means it can be used in both America and Europe, as well as in some other countries. The Treo 700 models, sold by Verizon and Sprint, and the Q, sold only by Verizon, use an American technology called CDMA that doesn’t work in Europe or in most places outside the U.S.

However, that GSM technology also saddles the E62 with its biggest drawback: It is much slower at receiving data such as email and Web pages than the Q or the Treo 700, or even certain BlackBerry models. That’s because it uses EDGE, a GSM variant that has been blown away by a technology called EVDO used by the Treo 700 and the Q. In my tests, EVDO has been up to seven times as fast as EDGE.

The E62 also lacks a camera, unlike the Q and the Treo 700. But, like them, it has Bluetooth wireless technology.

Nokia has built in a sharp, vivid screen with a resolution of 320 by 240. That’s better than the resolution on the Treo 700w and identical to the Q’s screen resolution — but inferior to the resolution on the Treo 700p.

The new Nokia is a bit larger than the Q — wider, thicker, longer and heavier. But it’s thinner and lighter than the Treo 700, albeit a bit wider and longer.

In my tests, the voice quality of the E62 was very good. Battery life was decent, with a talk time of between four and 5.5 hours. The phone accepts memory cards for storage of files and applications.

The BlackBerry Connect service and software, likely to cost around $45 a month, worked well. After I installed the BlackBerry software on the new Nokia and configured the service on the E62 and on an accompanying Web site, the service “pushed” all emails from my regular account to the E62 reliably. There’s no limit to how much email you can receive, though the carrier may intervene if it believes you are abusing the service.

The only downside of the BlackBerry Connect feature is that there’s a noticeable latency when you open an email before it displays on the screen.

In my tests, the N62 could open most major email attachment types, including Word documents, Excel spreadsheets and Adobe PDF files. It’s also supposed to work with PowerPoint presentations, but in my tests, this function failed.

The user interface on the E62 isn’t nearly as fast or slick as on the Palm operating system used by the Treo 700p. But I preferred it slightly over the Windows Mobile operating system used on the Treo 700w and some other smart phones. There were still too many menus and extra steps compared with the Palm system, but at least you can delete an email with one click. Turning on the speaker phone was also quick and easy.

I was able to synchronize the E62 with Microsoft Outlook, and bring over my contacts and calendar, using the separate Windows software that comes with the phone. And I was able to load up the memory card with pictures and songs from my computer and use them successfully on the E62.

All in all, the E62 is a solid and inexpensive smart phone.

Some cellphones already are able to play songs copied from computers, or streamed from an online radio-type service. And cellphone carriers have long sold snippets of songs as ringtones, which can be downloaded onto phones. But the new Sprint Music Store, unveiled by Sprint Nextel a couple of weeks ago, is the first service that allows complete songs to be purchased and downloaded directly from a cellphone, without a computer.

This Sanyo 9000 downloads songs.

This is a potentially big deal, because many more people carry cellphones all the time than they do iPods or other portable music players. And they can use their cellphones in places where they can’t easily use a PC. The much-touted Apple-Motorola ROKR phone, introduced earlier this fall, doesn’t let users access the iTunes store.

I have been testing the new Sprint Music Store and found it works well. The user interface is clean and simple, even on a small screen. The downloads, and playing of previews, are very fast over Sprint’s new broadband-class Power Vision network, which is required to use the music store, though it’s deployed in only parts of the country so far. Song playback sounded good on both phones I tested.

Unfortunately, Sprint and the record labels have decided to spoil their breakthrough service by setting a stratospheric new price for the legal download of a single song: $2.50. That’s 2.5 times the 99 cents that Apple and others charge on their online stores for a better-quality version of the very same song. Right now, Sprint is offering the first five downloads free, but starting with the sixth song, the $2.50-a-song price kicks in. The charges show up on your cellphone bill.

Sprint says its higher price is justified by the convenience factor, the ability to buy a song on the go, when the impulse strikes. The company compares this to paying more than usual for milk at an all-night convenience store, or for hot dogs at a ballpark. Also, Sprint contends, there are many people who find PC-based music stores too hard to use, and they will be willing to pay more for something simpler.

I believe something else is at work here: a lethal combination of two industries many consumers believe typically charge too much. One is the bumbling record industry, which has been seeking to raise prices in the fledgling legal downloading market even as it continues to bleed from free, illegal downloading. The other is the cellphone carriers, or, as I like to call them, “the Soviet ministries,” which too often treat their customers as captive and refuse to allow open competition for services they offer over their networks.

These partners in high prices already charge $2.50 for a small clip of a song to be used as a ringtone; so on some level, charging $2.50 for a whole song must seem like a bargain to them. But ringtones require editing, at least, and sometimes must be matched to a particular phone. With full-song downloads, Sprint is entering an established, competitive market where the price has been 99 cents. I could swallow a small convenience surcharge of, maybe, 25 cents, but not a 150% markup.

The high costs don’t stop there. The new music store can be accessed — so far — on only two new high-end phones, from Sanyo and Samsung, which cost more than $200, even after rebates. Even then, if you want to store more than about 32 songs on your phone, you’ll have to spring for a larger memory card, which costs anywhere from $25 to $100. You have to pay at least $15 a month for a data plan that allows you just to access the music store, though you also get other services.

For that kind of money, you’d better really, really, really want to download that new Kenny Chesney song, RIGHT NOW, before you can get to a computer.

Not only that, but the Sprint store imposes more limitations on the use of the songs than Apple does. You can play downloaded songs on only one phone, and the song files can’t be played back on a PC. To play them on a PC, you have to download them again, on the computer, in a different format, though you don’t get charged again for this.

The computer version of the songs can be played only on three PCs (Windows only), and three portable players, but not the most popular and best player, the iPod. Songs bought from Apple can be played on up to five computers and on an unlimited number of iPods.

Oh, and did I mention that Sprint offers only 250,000 songs, for now, compared with Apple’s selection of two million tracks?

Sprint did a good job designing this first mobile music store. It’s a shame that the store’s high prices and overdone restrictions make it impossible for me to recommend it, except for those with deep pockets and little patience.

The standard BlackBerry hand-helds from Research In Motion make clunky phones, and the slimmer BlackBerry 7100, while an acceptable phone, lacks a full keyboard. The models using Microsoft’s hand-held software have either lacked keyboards altogether or been too large to make comfortable phones. In contrast, the Treo is both roomy enough to be a good hand-held email device and compact enough to be a good phone.

Starting today, Verizon Wireless will introduce in the U.S. the first Microsoft-based smart phone with a built-in keyboard that is about the same shape, size and weight as the Treo. This new phone, the $599 Samsung i730, has one major capability the $399 Treo lacks — the ability to surf the Web and to send and receive email at broadband speeds.

The new Samsung can operate at speeds roughly comparable to home digital subscriber line, or DSL, connections through Verizon’s wireless Broadband Access network, which works on a wireless technology called EVDO. Or it can use speedy Wi-Fi wireless networking at places like coffee shops and airports.

I don’t expect to see an EVDO-capable Treo until very late this year or early in 2006. And the Treo lacks Wi-Fi capability. So the Samsung is the fastest email and Web device with a built-in keyboard that is small enough to be used comfortably as a phone. It will be available starting today for corporate customers and will be in Verizon stores in a couple of weeks.

Samsung i730

I have been testing the new i730 and comparing it to the Treo 650 from Sprint that I carry as my own phone. The Samsung worked as promised for making voice calls, accessing Web sites, and sending and receiving emails. It also played music and videos and displayed photos, though unlike my Sprint Treo, the configuration Verizon sells lacks a camera.

In my tests, I was able to get on the Web with the i730 at speeds ranging from 220 kilobits a second to 534 kilobits a second, which is between three and eight times as fast as the Treo’s average speed of 70 kilobits a second. And that was on the Verizon EVDO network, which is available in most major U.S. cities. Using the phone’s Wi-Fi capability, in my home and at a hotel, I was able to push the speed to nearly 700 kbps.

There were some things about the i730 that drove me nuts compared with the Treo. It has much worse battery life. The Microsoft Pocket PC software it uses is much harder to navigate one-handed, as phones should be used, than the Palm software on the Treo. Even when doing simple tasks, i730 users will have to employ the stylus, and two hands, far more often than Treo users do.

Unlike the Treo, whose keyboard is always visible beneath a square screen, the i730’s keyboard is hidden beneath its rectangular screen and slides out for use. The keys are a little more widely spaced than the Treo’s, though they are flatter and less pronounced. I found typing on the i730 to be about as fast as on the Treo.

The new Samsung isn’t quite as small as the Treo, but it is close. With its keyboard tucked out of sight for making phone calls, it is slightly narrower than the Treo but slightly thicker and longer. It also weighs a bit more. However, when the Samsung’s keyboard is slid out for writing email, it becomes far longer. To dial a call without the keyboard extended, you have to use a virtual number pad on the screen.

The i730’s screen is larger, but it offers less resolution than the Treo’s. Both phones use a five-way navigation pad, four buttons for calling up various functions, and traditional red and green buttons for starting and ending phone calls.

The Samsung has 64 megabytes of memory, double the Treo’s internal capacity, though this is offset by the fact that its Microsoft software needs more memory than does the Treo’s Palm software. Both phones accept standard SD memory cards. I was able to pop the memory card from my Treo into the Samsung, and it played or displayed the music and photos I had stored there. Unlike the Treo, the Samsung has stereo speakers.

Like the Treo, the Samsung offers Bluetooth wireless networking, a short-range technology for use with some cars and wireless headphones and for synchronizing data with PCs.

In addition to its increased need for the stylus and two hands, the i730 has some other drawbacks. In my tests, its standard battery died in far less than a full day and far faster than my Treo’s battery, which typically lasts me for a whole day of moderate phone-call use and heavy email use.

You can’t use the Samsung’s Wi-Fi and cellphone capabilities at the same time, and it can’t hand off your Internet connection from one wireless technology to the other. And, unlike my Sprint Treo, the Verizon i730 can’t be used as a modem for a laptop. These limitations probably stem more from business decisions by Verizon than from technological limitations.

Finally, the i730 is $200 more than the Treo 650. But if you prefer Microsoft’s software to Palm’s or crave having wireless broadband in a phone, the Samsung i730 is a good choice.
