This year, that tower of babble is higher than ever, as new terms have come into being, and old ones have come to the fore. So, here’s a quick glossary of some of the current techno terms you may encounter when shopping for a computer, television, digital camera or cellphone this holiday season.

Aero: This is the graphical user interface that’s a key part of Microsoft’s new Windows Vista operating system, due out around Jan. 30. If you want to get the full benefit of Vista, make sure any Windows PC you buy this season is capable of running Aero. Many are not.

Antiblur: Also known as antishake or image stabilization, this is a crucial feature of digital cameras today. Because few cameras have optical viewfinders, users tend to hold them at arm’s length to frame the shot on the LCD screen. This increases the likelihood of shaking the camera. An anti-blur feature can correct that. The best antiblur technology is optical. Digital versions are less effective.

Draft N: This is a new, faster, longer-range version of the popular Wi-Fi wireless networking system, and many new Wi-Fi products are built to comply with it. It succeeds the common “G” flavor of Wi-Fi. But, there’s a catch. As the name implies, this technology is based on a draft of the forthcoming new Wi-Fi standard, to be called “N.” And the final standard could be different enough to make Draft N gear outdated in 12 to 18 months.

Dual Boot: A computer that is configured to boot, or to start up, in two different operating systems, depending on which the user chooses at any one time. The most important example of this currently is on Apple’s Macintosh computers, which now can be set up to run either the Mac operating system or Microsoft Windows using Apple’s free dual-boot software, called Boot Camp.

Dual Core: A type of microprocessor — the brain that runs a computer — which packs the equivalent of two processors into a single chip. The best known dual-core processors in consumer computers are Intel’s Core 2 Duo and Core Duo, but rival AMD also makes them. They are a good bet for most people.

Flash Player: A small-capacity digital music player, like Apple’s iPod Nano and Shuffle. These players use flash memory, a type of memory chip that behaves like a small hard disk to store music, photos and videos. Larger players, such as the full-size iPod and the new Microsoft Zune, use actual hard disks, like the ones in computers. Flash memory is also what’s inside the small memory cards used in digital cameras.

HDMI: This acronym, for High-Definition Multimedia Interface, describes a new kind of cable for hooking high-definition TVs to things like cable boxes and DVD players. It provides a high-quality digital feed, and combines both audio and video signals via a single connection. When shopping for an HDTV, make sure it has HDMI connectors on the back.

HSDPA: An awkward name for a new high-speed cellphone network being deployed in the U.S. by Cingular Wireless. Its full name is High Speed Downlink Packet Access, and it’s intended to compete with successful high-speed networks from Verizon and Sprint called EVDO, or Evolution Data Only. All of these new networks allow Internet access at about the speed of a slow home DSL line, which is a big boost for cellphones. If you care about email and Internet access on a phone, and you are using Cingular, get a phone that can handle HSDPA.

Quad Band: A cellphone that handles all four bands, or frequencies, used in various countries by wireless phone companies adhering to a world-wide standard called GSM. Examples are Cingular and T-Mobile in the U.S., and Vodafone and Orange in Europe. A quad-band phone can be used on any GSM network anywhere, so if you travel overseas a lot, you may want one.

RAW: A file format for digital photographs that is uncompressed and largely unmodified by the camera’s chips, and therefore includes every detail of the color and image. It is prized by professional photographers and serious amateurs, who look for cameras and photo software that can handle the RAW format. But it produces enormous files, so most users should ignore it and stick with the very good, very common compressed photo format, called JPEG or JPG.

Shared Memory: A computer configuration in which the video circuitry lacks its own dedicated memory and must share, or drain off, a portion of the computer’s main memory. This is common in lower-price computers. It’s fine, but it reduces the amount of memory available to the nonvideo functions of the computer, so you may want to add extra memory to a PC of this type.

WAN: Any wide-area network, such as a cellphone network, that can be used to send and receive data. It is distinguished from a LAN, or local area network, such as the wired and wireless networks deployed inside a business or home. Some computer makers use the term for the built-in cellphone modems in their laptops.

Good luck with your gift shopping. Don’t get trapped in the tower of babble.

And the cellular broadband services, such as Verizon Wireless’s BroadbandAccess, can operate at speeds roughly equivalent to, and sometimes well beyond, the speed of basic wired home DSL service. That means you can surf the Web, and get email and large attachments pretty efficiently.

The card for the Verizon network

A small percentage of users hook up to these cellular broadband networks using laptops that have the necessary gear built in. Another small group uses a cellphone as a modem. But most users of these networks use external cellular-modem cards that plug into a standard slot on the side of their laptops. Therein lies a problem.

The computer industry is in the process of dumping that standard slot, called a PC Card slot, for a new, incompatible slot called ExpressCard. So, buyers of many new laptops are finding their cellphone modems are obsolete.

Now, Novatel, a leading maker of these cards, has come out with a couple of new ExpressCard versions for cellular broadband networks. One, which works on Verizon Wireless’s network, is already on the market, sold by Verizon and by Dell. The second, which works on Cingular’s BroadbandConnect high-speed network, will go on sale from Dell and possibly Cingular later this year, likely late November.

I have been testing the Verizon version of the card, called the V640, as well as a pre-release model of the version that works with Cingular, which Novatel calls the Merlin XU870. The tests not only gave me a chance to evaluate the cards themselves, but also to compare the Verizon and Cingular high-speed networks.

My verdict: The cards were easy to set up and use, and worked well. But the two high-speed networks are very different. While Cingular gave me higher speeds than Verizon in a couple of locations, the Verizon Wireless BroadbandAccess network crushed Cingular’s BroadbandConnect in most places I compared them.

This wasn’t a rigorous scientific test. I used two different laptops, an Apple MacBook Pro and a Dell Latitude D820. The Cingular tests were all conducted on the Dell, because the Mac software for the Cingular card won’t be ready until the card goes on sale. The Verizon tests were all conducted on the Mac. On both machines, I used the test service at speakeasy.net, accessed via the Firefox Web browser.

Also, I tested the cards in only Washington and New York City, and on Amtrak’s Acela Express trains in between. That is a heavily populated region; it’s also Verizon’s home territory, and Cingular might have done better in other parts of the country. Verizon has been rolling out its high-speed network since 2003; Cingular is well behind. Verizon offers the service in 185 metro areas; Cingular is in just 75.

Both cellphone carriers charge $60 a month for unlimited data service using the cards, if you have a voice plan with them. The new Verizon card costs $180. The new Cingular-compatible card is likely to cost $50 more.

The cards look nearly identical, and each works on both Windows and Macintosh computers. On Windows, you must connect using special software. On the Mac, you can simply use integrated software from Apple, if you choose. Both cards have small flip-up antennas and indicator lights. Both worked fine.

Verizon’s high-speed service is often called EVDO, for its underlying technology. Cingular’s service uses a technology called HSDPA.

In my tests, which involved about 20 head-to-head comparisons, the Verizon card and network averaged 818 kilobits per second “downstream” (to get Web pages, and to receive email and attachments) and 113 kbps “upstream” (to send email and files).

By contrast, the Cingular-compatible card averaged just 463 kbps downstream and 77 kbps upstream. Plus, during the three-hour train trip, Cingular disconnected me, or simply had no coverage at all, eight times. Verizon did so only once. Verizon has a deal with Amtrak that supplies data service inside the trains, which helped, but this in-train signal doesn’t include the high-speed EVDO service.

Cingular did beat Verizon in two places: my hotel in New York’s financial district and my office in downtown Washington. In the hotel, the Cingular service got a downstream speed of 1753 kbps — its highest in my tests — versus 888 kbps for Verizon and just 747 kbps for the hotel’s expensive wired Internet service. In my office, Cingular got 1133 kbps downstream versus 644 kbps for Verizon.

But the downstream speeds varied wildly. In Trenton, N.J., the Cingular service managed just 16 kbps. The best for Verizon was 1366 kbps in New York’s Penn Station, while its worst was 132 kbps between big cities in New Jersey.

I recommend both new cards. But unless you live, work and travel in very strong Cingular coverage areas, Verizon is the better choice for high-speed wireless data, at least today.

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.

I’ve been testing two new small and light laptops from these companies: the Sony Vaio SZ160, and the Lenovo ThinkPad X60s. Both weigh in at under four pounds, so they won’t break your back when you tote them on the road. But each has plenty of power, decent battery life and a rich set of features. And, despite their small size, these machines are capable of serious work, partly because both use Intel’s new Dual Core processor, which packs the equivalent of two processors into one.

I like both machines, but they have different benefits and downsides. The ThinkPad is the latest entry in a long line of small, rugged laptops with great keyboards and strong battery life. It has a speedy, optional, internal cellphone modem for connecting to the Internet over a cellphone network. But it lacks an internal optical (CD or DVD) drive.

At the cost of just a little more weight and size, the Sony I tested includes an optical drive and a bigger screen, but it lacks a cellphone modem and has weaker battery life than the Lenovo configuration I tested. For enhanced security, both laptops have built-in fingerprint readers that can bolster or replace typed passwords. Neither is a bargain-basement laptop. The Sony SZ series starts at $2,000, and the ThinkPad X60 series starts at $1,900. They come in many different configurations, and thus many different prices. The ThinkPad X60s I tested, which included a cellphone modem, an extra-strength battery and a dock with an optical drive, costs $2,300. The Sony SZ I tested, which didn’t include a dock, an extended battery or a cellphone modem — but did have that internal optical drive — costs $2,500.

The Lenovo ThinkPad X60s

The Thinkpad X60S I tested weighed 3.46 pounds, while my Sony SZ160 test model weighed just 3.72 pounds, even with the bigger screen and optical drive. The ThinkPad is 10.5 inches wide by 8.3 inches deep, and it’s between 0.8 inch and 1.11 inches thick. The Sony is 12.5 inches wide by 9.3 inches deep, and it’s between 0.9 inch and 1.3 inches thick. The Sony’s larger dimensions are mainly a result of its bigger screen — 13.3 inches, versus 12.1 inches for the Lenovo. The Sony screen is also higher resolution.

I put both laptops through my usual tough battery test, wherein I turn off all power-saving software, crank up the screen brightness to the max, turn on the wireless networking, and then play an endless loop of music.

My test ThinkPad, with its double-capacity battery, lasted a very impressive four hours and 49 minutes. In normal use, with power-saving turned on and a more typical work pattern, I’d expect it to last six hours or more, which is excellent. My test Sony, which had a normal-size battery, lasted just three hours and two minutes, even though the machine was running on its so-called Stamina setting. In normal use, the Sony would likely top four hours. Presumably, a Lenovo with a standard battery would do worse, and a Sony with an extended battery would do better.

Neither can match Apple when it comes to the quality of its built-in software. Lenovo’s is too geeky and is aimed more at corporate than consumer customers. Sony’s is more consumer-oriented, but it’s inconsistent and confusing.

The ThinkPad X60s, like its predecessors from IBM, is compact and rugged, with strong hinges and the best keyboard in any laptop. It has both built-in Wi-Fi wireless networking and a built-in cellphone modem that works on Verizon’s speedy EV-DO network.

My test machine worked well on all the typical computing tasks most people do, but there was one small defect in a Lenovo-supplied wireless software program that kept turning off the Wi-Fi. The company says this problem appeared only in early models like mine and has been fixed. Overall, the quality seemed as good as when IBM was making the machines.

The Sony Vaio SZ160

But the Thinkpad X series really should have an internal optical drive by now. When it was introduced, few ultra-small laptops had them, but since then Sony and others have figured out how to install optical drives in even smaller boxes.

The Sony SZ series is interesting because, while it’s not Sony’s smallest or lightest line, it packs a larger screen and an optical drive into a package that’s under four pounds. Like the Lenovo, it worked well at all typical tasks.

The SZ’s biggest innovation is that it has two graphics systems and the aforementioned “Stamina” mode, controlled by a switch, which allows you to use the weaker graphics hardware to save battery power. Its biggest downside is that its optional cellphone modem (available this summer in a pricier premium model I didn’t test) works on Cingular’s EDGE network, which is only about a seventh as fast as the Verizon network Lenovo uses.

You won’t go wrong with either of these well-designed laptops. For road warriors, they are worth their hefty price tags.

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.
