But every time I wanted to change songs, I had to go to another room and make a few mouse clicks on my computer. Ever since then, I’ve been waiting for someone to come up with a good, affordable remote control that lets me change tunes no matter where I am in the house.

Apple’s Remote program

It turns out, I already owned that device. It’s an iPod touch. A new program released by Apple (AAPL) in July was all it took to convert my MP3 player into a sophisticated remote control for my digital-music collection. That program, called simply Remote, runs on the iPhone as well as on the iPod touch, a version of the Apple MP3 player that has an iPhone-like touch-sensing screen and Internet-access capabilities using Wi-Fi wireless technology. Remote is available free of charge on the online App Store that Apple has used since July to distribute software for those devices.

In essence, Remote is a remote control for all music stored on a Mac or Windows PC that’s loaded into iTunes, Apple’s music jukebox software. It allows you to jump between playlists, browse artists and pump up the volume. For the program to work, you need to buy into using other Apple entertainment products.

In the simplest setup, Remote lets you control the music from stereo speakers connected directly to a PC. But it’s most useful when you use a PC to deliver audio to additional speakers around a home — say, a pair on the patio and in the living room.

Apple sells a couple of products that receive audio signals from a PC running iTunes. Both work wirelessly over a Wi-Fi home network so you don’t need to put holes into your walls to run computer and speaker wires. I tested Remote using both. One is an Apple TV, a $229 set-top box in my living room that plays digital audio and video through a standard home-theater system. The other is an AirPort Express, a $99 Apple wireless networking device on my patio connected to a pair of powered A5 speakers made by Audioengine, of San Jose, Calif. A third set of speakers was connected to an iMac in the kitchen, where I store all of my digital music. (The least expensive iPod touch costs $299.)

It was a breeze to configure the Apple TV and AirPort Express to show up as remote speakers in iTunes on my computer. Setting up Remote to give me mobile control over this array of speakers was trickier. After installing the program on my iPod touch, I couldn’t get it to work with iTunes on my PC. After 20 minutes of fiddling with the security settings for my Wi-Fi base station, iTunes finally recognized Remote. I was in business.

We all know how confusing the remote controls for TV sets and stereo systems can be. Remote, by contrast, cleanly displays all the music on my PC on the color screen of my iPod touch.

The program let me flip through artists, albums and playlists with simple finger swipes. But I was sorry that Remote doesn’t have a feature in the iPod touch called cover flow that lets users browse their music libraries by flipping through album-cover art. Apple says it may offer the feature in the future.

The software also let me easily turn on and off the music from my speakers in my kitchen, living room and patio. I could have all the speakers on at once — good for a party. The sound was terrific. The crisp-sounding $349 Audioengine speakers don’t require a stereo receiver.

Because Remote uses Wi-Fi to communicate with iTunes, I could control music anywhere around my house and backyard, which are small enough to be fully covered with a signal from my Wi-Fi base station. That’s a big plus over conventional remote controls that use infrared, a technology that doesn’t work through walls.

One drawback: The battery in my iPod touch drained overnight when I configured the device to stay connected to iTunes, a feature that increases software responsiveness. Changing the setting let me go days without recharging my iPod touch, but it meant I had to wait a couple of seconds for Remote to connect to iTunes when I started up the software — an acceptable trade-off.

Another multiroom audio product with a good remote control is the ZonePlayer from Sonos, an equipment maker based in Santa Barbara, Calif. That system has some advantages over Apple’s offerings, including the ability to access tunes from online music services, such as Pandora and Rhapsody, and separate volume controls for each set of speakers.

The Sonos system starts at $999 for a remote control and wireless receivers, without speakers, that can deliver music to two rooms.

For people who already own an iPod touch or iPhone, Remote is a good reason to buy an AirPort Express, and fill your home with music.

The new aluminum-clad MacBook Air, which I’ve been testing for several days, is billed as the world’s thinnest notebook computer. Its thickest point measures just three-quarters of an inch, which is slimmer than the thinnest point on some other subnotebooks. And it employs some innovative software features, such as fingertip gestures for its touchpad that are similar to those on Apple’s iPhone.

Apple refused to make the most common compromise computer makers employ to create their littlest laptops. Other subnotebooks — a category generally defined as weighing three pounds or less — have screens of just 10 to 12 inches and compressed keyboards. The three-pound MacBook Air, by contrast, features a 13.3-inch display and a full-size keyboard.

It’s impossible to convey in words just how pleasing and surprising this computer feels in the hand. It’s so svelte when closed that it’s a real shock to discover the big screen and keyboard inside.

But there’s a price for this laptop’s daring design: Apple had to give up some features road warriors consider standard in a subnotebook, and certain of these omissions are radical. Chief among them is the lack of a removable battery. So, while the MacBook Air will be a perfect choice for some travelers, I can’t recommend it for all. It really depends on your style of working on the road and what features you value most.

The MacBook Air, which will be available next week, costs $1,800 with an 80-gigabyte hard drive and a generous two gigabytes of memory. A second model, with a faster, cutting-edge, 64-gigabyte, solid-state drive and a slightly speedier processor, costs a whopping $3,100. The $1,800 price for the main model isn’t unusual in subnotebooks, which can easily top $2,000, although some competitors cost less.

In my tests, the MacBook Air’s screen and keyboard were a pleasure to use. The machine felt speedy, even with multiple programs running. And the laptop has the same Leopard operating system, superior built-in software, and paucity of viruses and spyware that I believe generally give the Mac an edge. I was able to install and run Windows XP using the third-party Parallels software.

But then there are those trade-offs. The sealed-in battery means you can’t carry a spare in case you run out of juice, and you have to bring it to a dealer when you need a new one. There’s no built-in DVD drive. The thin case can’t accommodate a larger internal hard disk. And the machine omits many common ports and connectors.

The MacBook Air

There’s no Ethernet jack for wired broadband Internet connections and no dedicated slot for the most common types of external cellphone modems. That means that out of the box, the MacBook Air has only one way to get on the Internet — through its fast, built-in Wi-Fi connection. If you’re out of Wi-Fi range, you’re out of luck, unless you buy an optional, $30 add-on Ethernet connector or a cellphone modem that connects via USB.

In fact, the MacBook Air has only three connectors: a headphone jack, a single USB port and a port for connecting an external monitor.

That single USB port is a problem, because so many peripherals use USB. You can buy a tiny, cheap USB hub that adds three more ports, but that’s yet another item to carry.

The lack of a DVD drive is partly solved by some clever software Apple included that lets you “borrow” the DVD drive on any other Mac or Windows PC on your network, so you can transfer files or install new software from a CD or DVD. This worked fine in my tests, in which I installed several new programs from CDs on remote computers, but it requires disabling third-party firewalls on Windows machines. It also doesn’t work for installing Windows on your Mac, for watching DVDs, or for playing or importing music. For those tasks, you need an external DVD drive. Apple sells one for $99.

In my standard battery test, where I disable all power-saving features, set the screen brightness at maximum, turn on the Wi-Fi and play an endless loop of music, the MacBook Air’s battery lasted 3 hours, 24 minutes. That means you could likely get 4.5 hours in a normal work pattern, almost the five hours Apple claims.

But the MacBook Air has another downside: its screen height. Because of the larger screen, the lid stands higher when opened than on most other subnotebooks. So it isn’t as usable as some competitors when the seat in front of you in coach on a plane is reclined.

If you value thinness, and a large screen and keyboard in a subnotebook, and don’t watch DVDs on planes or require spare batteries, the MacBook Air might be just the ticket. But if you rely on spare batteries, expect the usual array of ports, or like to play DVDs on planes, this isn’t the computer to buy.

The latest versions of the devices are getting smaller in size, compared with the old ones, and have more features. You can use them to scan photos, ID cards and checks, among other things — just so the item is no more than slightly bigger than card size.

I have been testing two products: the OptiCard 821 from Plustek Technology, of Cerritos, Calif., and the IRISCard Pro 4, from Belgium-based Image Recognition Integrated Systems, or I.R.I.S.

Plustek’s OptiCard 821

I found that both scanners have a quick and easy way to organize business-card information, but their software isn’t as easy to work with when manipulating the resulting digital images. Also, the machines work best at their originally intended task, and so are better at scanning business cards than at scanning photos, for example.

The software in both devices, overall, created clear images of the names and numbers from most of the typical cards; that is, those cards written with dark ink against a light background. The scanners did a poor job when they had to read cards that were printed on dark-colored stock.

Installing the software was easy enough, and took only a few minutes. After inserting the software CD into your computer, small pop-up windows open to guide you through the process. When the installation is finished, you connect the scanner to your computer’s USB port with the cord provided.

To begin scanning, you just feed the cards into a front slot on the devices and push the scan button. The scanners pull the cards across the scanning head and spit them out the back, saving the cards in the process.

The first time you use the scanners you will be asked to calibrate them to set the parameters for color, shadows and light. It’s an easy task: You just insert a special card that comes with the packages.

The scanners’ software can recognize and categorize cards written in several languages, including Spanish, French, German, Italian, Arabic and Chinese. Scanning a business card using either machine didn’t take more than five seconds; photo-scanning took much longer.

Both machines have two buttons on the top for scanning and for further customizing the scan. The scan buttom has a few standard configurations for capturing the image from the card and transforming it into a PDF file.

The custom button begins with the same process, but then allows you to manipulate the results. When I inserted a card into one of the scanners and pressed the custom button, a window pop-up opened for me to choose details such as language, color, dimensions, the specific file to which I wanted to send the image and the storage format.

You can edit the cards as you store them and make any fixes you might have from botched scans. The images are saved in the folder you chose when you configured your scanning options. You can opt to arrange them just alphabetically, too.

The scanners come with software that can help make the scanning and organizing process more efficient, but could also be a bit confusing for some users because of all the choices.

To test the new OptiCard, which costs $150, I processed 20 random business cards with white backgrounds. I found that scanning was swift; 13 white-background cards came out perfectly or with such minor glitches that they didn’t require any editing. An additional four needed some editing but fixing them didn’t take more than a few minutes. Three cards needed major retyping, replacing missing numbers and redoing a name that got scrambled into a phone number.

I also tried scanning two dark-background cards but to no avail. One didn’t come out at all and the other had black splotches.

I found the $200 IRISCard Pro 4 slightly more accurate in scanning textual information from the same 20 cards. Only two needed minor editing — replacing a hyphen with a comma, for example — and just one card required major retyping, replacing skipped information. The scanner, however, was no better at the dark cards.

I also scanned a couple photos in both devices, but the copies were too blurry to save.

Both scanners are smaller than many TV remote controls. The OptiCard is 1.5 inches high, 6.9 inches wide and 2.4 inches deep. The IRISCard Pro 4 is 1.3 by 6.2 inches and is two inches deep. I was able to take them to work in one of my jacket pockets. I could imagine bringing the device along for a days-long seminar to keep up with card-collecting. Both are compatible with Windows PCs and Macs.

While the interface between the scanners and the user’s contact data program could offer more features to make organizing easier, these tools are worth a try. At least you can get those cards off your desk before the pile topples.

But for some folks, getting the most out of these players takes too much work or too much money. Converting CDs to music files takes time, as does selecting and downloading tracks from online music services, and synchronizing players with PCs. Creating great playlists also takes time and effort. Some people prefer the old radio model, where songs are programmed by somebody else and you just listen.

Plus, whether you download songs for 99 cents apiece, use a subscription download service for $15 a month, or sign up for satellite radio at $13 a month, the costs to keep your portable player filled legally can add up quickly.

So a new kind of portable player, one for more passive and budget-minded users, is slated to arrive late next month. It’s called the Slacker Personal Radio, and its name is meant to refer to people of any age who just want to sit back and listen instead of actively managing their music.

The new Slacker players will come in three models, ranging from $200 to $300, depending on capacity. But the music they play will be absolutely free, contained in preprogrammed Internet radio stations instead of individually selected songs and albums. The stations will be automatically refreshed with new tunes via a wireless connection built right into the device. You’ll have to be near a hot spot for these updates. But you won’t need a hot spot just to hear your music, because the songs are cached on the device. And you’ll never have to plug it into a computer.

The player is tied to Slacker’s free Internet radio service, slacker.com, which is already up and running, and allows you to listen to music via any standard Windows or Mac Web browser. Using the service, you can personalize your player by selecting from over 100 canned stations or by creating stations based around any of 10,000 artists. These stations will be beamed to your player wirelessly. You can even choose which stations are loaded onto your player before the company ships it to you.

The company, a San Diego-based start-up of the same name, hopes to make money eventually via advertising on the player, and by selling an optional paid premium plan that offers some additional features.

I’ve been testing a prototype of the chunky, black plastic Slacker player, which is dominated by a four-inch color screen. It has two redundant navigation systems: a touch-sensitive strip at the side of the screen and a wheel on one edge. It provides a rich listening experience, including album art and other photos, artist bios and album reviews. The sound is good, and the Wi-Fi wireless connection worked in both my home and office.

The two prototype Slacker units I tried, however, were hobbled by bugs and glitches that the company must expunge by the release date, which was originally slated to be this month. For instance, the players sometimes failed to wake up after going to sleep, requiring a reboot. The touch strip was unreliable. One player failed several times to connect to my account. Battery life is well below Slacker’s goal of 12 hours between charges. The company says it is aware of these problems, and pledges all will be fixed.

Slacker isn’t the only portable player to offer programmed Internet stations. The Rhapsody service offers similar, customizable Internet-based stations on a couple of players. And both the Sirius and XM satellite-radio networks offer portable players for listening to their stations, although the stations can’t be customized. But all of these players require monthly subscription payments, while Slacker’s stations are free.

The Slacker Radio

Because Slacker is based on Internet radio, it has some limitations imposed by the rules governing that format. For example, you can’t specify a particular song to play, or skip back to repeat a song. And you can skip ahead only six times per station per hour. Even if you create a station around a particular artist, the station will mainly be filled with artists the service considers similar. Songs by the artist you selected will be played only four times every three hours.

The player has a “heart button” for designating a song for frequent play and a “ban” button to eliminate the songs you hate.

If you’re willing to pay, or put in more effort, you can get additional capabilities. For example, Slacker players can hold and play some of your own songs, in addition to programmed stations, if you download a free Windows software program. And, if you sign up for the premium option at $7.50 a month, you get unlimited song-skipping, no ads, and the ability to save favorite songs on the device and play them as often as you like.

But the basic idea of Slacker is to make portable listening free of effort and of service charges. If the company can wring the bugs out of its new player and if its ads aren’t too annoying, that formula may appeal to some busy music lovers.

There are “universal” remotes that are designed to let you operate multiple electronics devices from a single control. But most universal remotes, if you can figure out how to work them at all, don’t help much with the tedious sequence of button pushes often required to do simple tasks, like watch a movie. In my case, just turning on the TV can require up to six punches on two different remotes, depending on what activity I happened to be doing on my home-theater system the last time I shut it off.

Logitech International, the Swiss computer-accessory maker, has come up with an answer to the problems of remote-control clutter and excessive button-pushing with its family of Harmony universal remote controls that are relatively affordable and easy to use.

The Harmony 1000

I tested two of the latest models of Logitech remotes, the Harmony 890 and 1000, and found that they greatly simplified using my home-theater system, despite a few flaws.

It’s a challenge just getting many universal remotes working, considering all of the electronics gear that occupy many TV rooms. The setup usually involves punching arcane codes into a universal remote corresponding to your electronics devices after looking the numbers up in a manual — a tedious process with lots of opportunity for failure.

Users configure Harmony remotes through what I found to be a far more user-friendly process: by tethering them to a Mac or Windows PC with a USB cable. A software program that comes with the remotes asks users what types of devices they’d like to set up, such as a home-theater receiver, a television set and a digital video recorder. Users will need the model number for their devices.

Once you’ve entered the model numbers into the Harmony program, the software automatically downloads all of the commands required to configure the remote so it works with your TV-room gadgets from an online Logitech database containing more than 200,000 devices — far more than you’d find listed in the manual for a conventionally programmed universal remote control. The Harmony software easily located all of my devices in its database.

An important feature of the Harmony remotes is something called activities, which lets users reduce to one the multiple button pushes typically required to do basic functions with their entertainment systems, such as watching a DVD. Logitech didn’t invent this concept, but it has made the setup process easy enough so users don’t have to hire a professional installer to do it for them, as is the case with many other high-end universal remote controls.

Based on the types of devices I told it I had, the Harmony software on the PC recommended a handful of activities for my remote controls, including “Watch TV,” “Watch a DVD,” and “Listen to CDs.”

To watch a DVD on my entertainment system, I normally need to turn on my TV and set it to the correct video input source, turn on my home theater receiver (which I use to play audio when watching movies) and turn on my Xbox 360 game console (through which I play DVDs) — a process that requires up to seven button pushes on multiple remote controls.

The Harmony remotes eventually allowed me to push one button to turn on all of these devices, but there were hiccups. When I hit the “Watch DVD” activity button, the Harmony remotes initially turned on all of my devices except the Xbox 360. After a few minutes exploring the Harmony software on the PC, I was able to change a setting to correct the problem and update the remote.

In all, it took me about 30 minutes to configure the first Logitech remote I used, the Harmony 1000, and half that time for the Harmony 890, after I had become familiar with the process.

The two models of remotes offered similar functions but in radically different industrial designs. The Harmony 1000 is a tablet-shape control about the size of a small picture frame, with a large touch-sensitive color screen that displays large buttons for accessing activities and other functions on your devices. The Harmony 890 is a more conventional wand-shape remote with a smaller screen.

I preferred the design of the Harmony 890, finding it easier and more natural to use with one hand, not to mention a better value. I have found the Harmony 1000 selling for as low as $272 and the Harmony 890 for $222 on Amazon.com. The 890 comes with a kit that lets you extend the range of the remote by using radio frequency, instead of infrared, signals.

Both Harmony remotes, though, made it much easier for me to use my entertainment system and cleaned up some of the clutter in my living room.

I’ve been testing two of the latest efforts to crack that problem. The first is from Toshiba, a company that once dominated the laptop world, but has since slipped badly. The other is from Dell, best known for larger, clunkier laptops. Both machines are stylish and worked fine in the tests, but each has flaws that might give a buyer pause.

These two new laptops, which use Intel’s Core 2 Duo processor, are very different in size. The Toshiba Portege R500 weighs just 2.4 pounds, has the footprint of a standard sheet of paper and is only about ¾-inch thick at its thinnest point. Yet it squeezes in a DVD drive. It sports a 12.1-inch widescreen display with very good resolution. The screen is lit by LEDs instead of by traditional lamps. That makes for more brightness and saves power.

The Dell XPS M1330, while still relatively small, is larger than the Toshiba. It weighs a hair under four pounds, has a larger footprint and is thicker. It falls into a hot new laptop category that features 13.3-inch widescreen displays — a size considered a good compromise between the small displays on the lightest laptops and the larger ones on the heavier models. The M1330 has some very un-Dell-like aspects to it, such as a choice of three lid colors and a slot-loading DVD drive that doesn’t require a pop-out tray.

Toshiba claims the R500 is the world’s thinnest notebook with a built-in DVD or CD drive. Dell claims the optional LED version of the M1330 is the thinnest with a 13.3-inch screen.

The Toshiba starts at $1,999 for a unit with a 120 gigabyte hard disk, a gigabyte of memory, and built-in Wi-Fi and Bluetooth wireless networking. The Dell starts at $1,299 for a model with a 120 gigabyte hard disk, a gigabyte of memory, built-in Wi-Fi (but not Bluetooth) and standard display. An LED display costs $150 more; Bluetooth is an extra $20.

I tested the base model of the Toshiba R500 and found that it performed well. My particular machine came with Windows XP, though Windows Vista is also available in a model that costs $150 more. The tiny silver computer handled everything I threw at it, including Microsoft Office, the Firefox Web browser, the iTunes music program and more.

Toshiba’s Portege R500, top, and Dell’s XPS M1330

In my tough battery test, where I turn off power-saving features, maximize screen brightness, turn on Wi-Fi and play an endless loop of music, the R500 lasted an impressive three hours, 44 minutes. I estimate that in more normal use, you could get five hours of battery life.

But my test Toshiba, a production unit, had a major flaw: The DVD drive didn’t work. Apparently, the lens on the drive had come loose in shipping. Toshiba sent another unit with a working drive, but this is a major issue because the machine uses a new, very thin type of DVD drive that seemed fragile to me.

In fact, the R500 lacked a solid feeling overall. The keyboard was OK, but the touch-pad buttons seemed flimsy and stiff, and I had the impression that this was a computer you’d have to treat gently. It also had trouble reconnecting with my Wi-Fi network after waking up from its sleep state. And it was loaded with the trial software and offers I call craplets.

The Dell XPS M1330, on the other hand, felt solid through and through. From its crimson cover to its wedge shape, it’s also a handsome laptop. The unit I tested had the LED screen and a full complement of options, which would have brought its price to $2,188.

Like the Toshiba, the Dell speedily handled Microsoft Office, Firefox, iTunes and other software. Its Wi-Fi worked very well. My test model used Vista, and had the extra memory and souped-up graphics Vista needs to work well. The M1330 isn’t available with Windows XP. To Dell’s credit, it can be ordered with no craplets on it, for no extra money. But because it uses Vista, it starts up painfully slowly. A reboot took more than four minutes.

The big flaw on the Dell is battery life, a major downside for a machine meant to travel. In my test, the M1330 lasted just two hours, 27 minutes; so, you’d be lucky to get 3.5 hours out of it in normal use. Dell says the base model would do better because it has a wimpier, but less power-draining graphics system. You can get a bigger battery for $30 more, but it makes the machine larger and heavier.

The Dell XPS M1330 is a good, solid, mobile computer that needs better battery life and can get expensive once you start ordering options. The Toshiba R500 seems like a dream machine for travelers, but its DVD defect is worrisome and you may have to treat it like glassware.

Many of these services promise to keep the authors’ autobiographies and biographies online forever. It is up to the writers whether they want to limit readership with the use of passwords or to make their stories available to the world.

I tested two of the sites: LifeBio.com and biowriters.NET. Both proved helpful in organizing key parts of my life and prompted me to remember important moments, people and situations — some of which I would prefer to forget.

But when it came to a finished product, the results were a little disappointing, especially when I opted for the least expensive choices. Those left you with little more than a list of disconnected sentences about yourself and your recollections.

People who have no writing skills but who want to create stories with a gripping narrative are going to have to pay up. Biowriters sells a 14-chapter biography compiled by a professional writer for $3,450.

To get started with either of these services, you first need to sign up online to get a member ID and password. You’ll need to use the password whenever you want to access your online biography.

LifeBio’s online interface is intuitive. Its template is divided into four main headings containing many areas of interest, including historical events and favorites as a child. Each heading is subdivided into groups of questions. You click on an entry and select the questions you want to answer, save your answers, then go on to other questions.

The service offers three types of membership. The entry-level InstantBio membership for $9.95 lets you answer 102 basic questions about hobbies, pets, high school and other obvious milestones in life. The basic membership for $39.95 has subscribers answering 250 questions divided into categories. The select membership is similar to the basic one except it also includes a memory journal, a hardcover book with 250 questions and space to answer them all. It’s designed for people who prefer to handwrite their biographies and not to broadcast them on the Internet. A select membership costs $49.95.

Many of the questions included in the basic membership are very general (”If you have experienced divorce or remarriage, you are welcome to share your memories and feelings.”); some are obvious (”Where would you go on dates?”); and some are thought-provoking and meant to allow you to give your life’s philosophy (”What advice would you give to future generations about love?”).

But unless you decide to try to weave all those answers into something resembling a real biography, you’ll end up with just your list of answers. The company’s InstantBio membership allows users to hide the questions but it still makes for a choppy narrative. LifeBio is testing a new approach that includes having a writer interview the members by phone. The end package would include an audio recording of the interview on a CD and a printout — all for about $199.

Signing up for biowriters online also is simple. You just click on the My BioWriters icon on the main page and create a password. You are then routed to your own home page with three headings: My Bio, where you can answer questions about your life that are divided into chapters; My Media, where users can upload pictures and PDF files; and My Purchases, where you can buy the company’s products.

This service offers a variety of payment options. Users can pay a $10.95 monthly subscription fee for the duration of the writing process, for which you answer 370 questions, upload pictures and other documents, and access the company’s writers, who will correspond by email or phone. Or you can pay $34.95 and have a lifetime of access.

Like LifeBio’s main memberships, biowriters’ basic final product is a list of answers to questions and a brief online synopsis biography. If you want the company’s writers to turn your answers into a real biography, biowriters charges $485 per chapter.

Biowriters also offers a service where users get a binder questionnaire and a recorder to have their stories later transcribed by professional writers. The transcription service costs $225. When finished, users ship everything to the company, which then will assign you a writer.

With both services, you can write as much or as little as you wish in response to the questions. Biowriters is more expensive than LifeBio but has more package options and tools, such as the transcription service and the writing assistants. Biowriters’ staff members will help users review, edit and put together a final product that looks more or less like a professional job.

Windows XP to Windows Vista: Microsoft has built a decent migration utility into the new Vista version of Windows. It’s called Windows Easy Transfer. It allows you to migrate folders and files, email accounts and messages, settings and favorites.

Windows Easy Transfer can be used to manage a migration over a network, via burned CDs or DVDs, or with external hard disks. But I tested it only with the simplest approach, the one Microsoft recommends: a special cable called an Easy Transfer cable. The best known of these is made by Belkin. It costs $40, and is available in electronics stores and from www.belkin.com/easytransfercable/. It works only if your old computer is running the very latest version of Windows XP, called SP2.

In my test, I first installed the software for the Belkin cable on my old Windows XP machine (Vista can handle it out of the box). I then plugged in the cable and used Windows Easy Transfer on both machines, following the instructions as I went along. The process was simple and quick. It transferred over 11,000 files totaling 10.9 gigabytes — documents, music, pictures, videos and more — in about 40 minutes. The files and settings were placed in a new user identity on the Vista PC.

Windows Easy Transfer even lets you select which items to move — and which to skip, if you want. But there are some downsides. Windows Easy Transfer doesn’t move programs, so you will have to reinstall these manually. Microsoft is testing a program that will move programs, called Windows Easy Transfer Companion. You can download it at Microsoft.com/downloads.

Also, I got a blue-screen crash shortly after the transfer completed, but the computer worked after a restart.

I also tested another program that can use the Belkin cable (or a similar cable sold by its publisher), PCMover by Laplink Software. It costs $50, or $60 with the cable, but has the advantage of moving programs, as well as files and settings. In my tests, it worked fine, transferring roughly 23 gigabytes of programs and files in about three hours. It also set up a new user identity on the Vista PC for the transferred material.

However, PCMover can only move all of your stuff. It doesn’t allow you to choose which items to move.

Worse, one of the transferred programs wouldn’t work on the Vista computer because it lacked some underlying components. Moving programs this way is a hit-or-miss proposition, because of the hideously complicated manner in which Windows stores programs on the hard disk and because some Windows programs won’t “activate,” or run, on a PC other than the one on which they were first installed.

Another alternative is a retractable cable called The Tornado, which costs $60 at www.thetornado.com. The beauty of this product is that it requires no software installation; the software is built in and just appears when you plug in the cable. The downside is that the software is entirely manual. You have to select, then drag and drop, folders and files between two windows representing the two computers.

In my tests, it worked fine, but was tedious. And unless you’re a techie, you wouldn’t be able to use it easily to transfer settings and programs, because you wouldn’t know where to find all of the files needed.

Windows XP to Macintosh: If you bought a new Apple Macintosh, instead of a Vista PC, the process of moving your files is even easier. No cable is needed. When you buy a Mac in an Apple retail store, Apple will transfer your pictures, music, movies and other documents from your Windows PC to your new Mac free of charge. If you bought the Mac elsewhere, including Apple’s online store, an Apple retail store will perform the data transfer for $75.

If you plan to run Windows on your Mac using the $80 Parallels software, from Parallels, the company will soon release the final version of a utility called Transporter. This program can transfer all the contents of a real Windows PC into the Windows environment on a Mac. But it works only over a network, and the files it moves won’t be easily accessible by Mac programs. Details are at www.parallels.com/products/desktop/transporter/.

I haven’t tested either of these procedures.

Macintosh to Macintosh: For years, all new Macs have come with an excellent built-in migration utility that, in my experience, is simple, quick and comprehensive. It works via a Firewire cable available for as little as $4 at electronics stores. It moves all types of files, settings and even programs, and lets you choose which types to move. I have used this process multiple times in recent years. It has never failed me, and typically has required two-to-five hours.

Whatever computer you buy, migration is now easier than ever, if not perfect.
