I haven’t tested campusbackup.org, whose Student Backup service copies an unlimited quantity of word-processing, spreadsheet, presentation and PDF files, once nightly, to a remote server for $50 a year. But there are other, more versatile options I have tested that, unlike Student Backup, copy photos and music and other types of files. These include MozyHome ($4.95 a month for unlimited storage, at mozy.com) and Carbonite ($55 a year for unlimited storage at carbonite.com). All three work with either Windows or Mac computers.

I read that importing the newly remastered Beatles CDs into iTunes and listening to them on a computer or portable player is like buying a masterpiece and staring at a photocopy of it. Any truth to this? Does importing really lose that much quality?

It depends on how sensitive an ear you have. In most cases, when you import a CD into iTunes or any other software jukebox program, you are converting the songs into a compressed file, such as an MP3 or AAC file. This saves a ton of space on your hard disk, but at least subtly diminishes quality. To an audiophile, that can make a big, negative difference, especially when you add the insult of listening to the music through iPod headphones or small computer speakers. To most of the rest of us, though—especially with rock, pop, urban or country music—it’s no big deal.

However, there is a compromise. If you don’t care about the songs taking up lots more space on your hard disk, iTunes will allow you to import them in a much less compressed format called Apple Lossless or an uncompressed format called WAV. You can choose which format to use in the iTunes Preferences settings. In the latest version of iTunes, called iTunes 9, this particular option is found under the General tab in Preferences, by clicking on the button called “Import Settings.”

Previously I had a Dell and Windows and used Family Tree Maker for genealogy records. Now that I’m an Apple owner, I find that Family Tree Maker does not work on an Apple, only Windows. What can I do about this?

It seems to me that you have three obvious options. If you still have your old Dell, you could crank it up again just for the purpose of running Family Tree Maker. Or, you could buy a boxed copy of Windows and install it on your Mac, which is fully capable of running Windows and Windows programs (assuming it’s an Intel-based Mac). Finally, you could switch to one of the native Mac-based genealogy programs and import your data from Family Tree Maker via the standard GEDCOM file format used in genealogy. One such program, called Reunion, includes specific instructions on importing data from Family Tree Maker on its “Top 10 Questions” page, at leisterpro.com.

In your review of Amazon’s Kindle 2 e-book reader, you didn’t say much about its ability to display newspapers, magazines and blogs. How does it do with this type of content?

The new model’s handling of periodicals and blogs is quite similar to that of the old model’s, which is why I didn’t dwell on it. This wasn’t an area where Amazon changed much.

While I know some Kindle owners happily rely on the device for newspaper reading, in my opinion, the Kindle doesn’t do as well with periodicals and blogs as devices like laptops and the best smart phones. Its ability to render the content optimally is limited by its low-power monochrome screen, and its navigation system is fairly primitive compared to that on a laptop or a good smart phone. Kindle’s features were built mainly for books, which, unlike periodicals, don’t contain links and prompt little navigation in most pages.

Whenever I watch an Internet movie, the monitor on my desktop Vista PC shuts off every 10 minutes unless I touch the keyboard. How can I solve this problem?

Unless your monitor has its own feature that turns itself off after some time period, this is usually easily controllable from within Vista. You simply need to go into the Control Panel, find the power settings, and set the option for automatically turning off the display to “never,” or to some very long interval. Remember to re-enable the screen dimming feature after you’re done with the movie, so you don’t waste energy. If this doesn’t work, check to see if the manufacturer has installed its own software for controlling power settings. If so, you may have to change the settings there.

I am retired and would like to buy a small, wireless computer for travel that would have email and Internet software and very few other applications. The keyboard would be bigger than a Blackberry’s and smaller than a laptop’s. Can you recommend something?

I would look for a so-called “netbook.” These are little laptops, with screens generally 10 inches or smaller, that usually weigh almost nothing and sell for under $500. They typically come with relatively slow processors and relatively limited storage, but every one that I’ve seen is wireless and does a decent job with email and the Internet. There are many models, from companies like Acer, Asus, Hewlett Packard, Lenovo and Dell.

Do you still recommend the Dell XPS One all-in-one computer that you favorably reviewed last December? I am not a techie at all but need to replace my 5-year-old Dell and was interested in an all-in-one.

Yes. In fact, I now own two of these Dell XPS Ones and use them as my Vista desktop computers, at home and in the office. I still believe, as I wrote in my review, that this Dell’s hardware is superior to that of the competing Apple iMac, though the Vista operating system is inferior to Apple’s. And the base XPS One now costs the same as the base iMac — $1,199 — instead of $300 more, as it did last year. So, if you want the Windows operating system, and like the look and convenience of an all-in-one desktop, I still favor the XPS One. You can find my review at tinyurl.com/2xw 6mv.

Will Apple’s new MacBooks and MacBook Pros run Windows directly without an intervening “virtual machine” program like Parallels or Fusion?

Yes. All Apple Macs running the current Leopard operating system, including the new laptops, come with the ability to directly run Windows XP or Vista. Using Apple’s built-in “Boot Camp” feature, you can start up the computer in Windows, instead of the Mac’s own operating system, which turns the Mac into a pure Windows machine, with no trace of the Mac operating system running. The upsides of this approach are maximum Windows speed, and compatibility with the most graphics-intensive Windows programs, including games. Note that, to run Windows on a Mac, you must obtain and install a fresh, boxed, full version of XP or Vista. Apple doesn’t supply Windows.

I have a Yahoo email account, and wonder if Yahoo allows receipt and storage of email directly via a computer email program, such as Outlook, or is it all Web storage? Can you do both?

Yes. Yahoo offers a “Plus” option, for $20 a year, that permits users to receive and store their Yahoo email using a locally installed, instead of Web-based, email program. This approach does work with Microsoft Office, as well as many other local email programs. And you can still use Yahoo’s Web-based email interface at the same time. The Plus option also includes other benefits, including the elimination of ads and a doubling of the size limit on individual messages, to 20 megabytes.

Do Macs last longer than Windows PCs? I am willing to pay the additional cost for a Mac if it will last significantly longer, but if it has approximately the same lifespan as a PC from a reputable manufacturer, I will stay with PCs.

In my years of using both types of computers daily, I have never noticed a significant difference in when Macs and Windows PCs become unfit to use, and I have never seen claims from Apple (AAPL) that its computers last longer than competing models. Obviously, on the Windows side, there’s a much greater variety of manufacturers and of quality levels, while Apple makes all Macs, and receives generally high marks in well-known surveys of reliability. But so do some Windows PC makers. All computer makers turn out the occasional lemon, and how long a computer “lasts” depends tremendously on how you use it and how you judge its usefulness over time.

My laptop hard drive crashed last year and I lost some digital pictures that were on it. My daughter had accidentally copied those digital pictures onto her iPod but she didn’t select the option to store them at full resolution. I know I can get the pictures back off the iPod, but is there any software that can get them back at full resolution?

Not as far as I know. Unless you tell iTunes to store the photo at full resolution, what is on the iPod is a version of the photo that has been scaled down for the iPod’s screen resolution and storage capacity, and that is the resolution they would retain if you copied them back to a computer.

I have an H-P (HPQ) laptop using Windows XP and Microsoft (MSFT) Office 2003. If I purchase a new H-P laptop with Vista and Office 2007, what must be done to make the two machines compatible? My goal is to be able to take a copy of Office files from one computer and use them on the other.

The difference in the operating systems won’t affect your plan, but the difference in the Office versions might. The newer 2007 version of Office can easily handle your files from the older version. But Office 2003 can’t handle files in the new default Office formats introduced in the 2007 version. These formats use file suffixes that end in the letter x. For instance, the new Word format has an extension of docx, instead of the old, familiar doc.

Luckily, the new Office can still save files automatically in the old formats, if you change a setting. Here’s how.

On the computer with the new version of Office, click on the round “Office Button” at the top left of the 2007 versions of Word, Excel and PowerPoint. Then, in the window that appears, click on “Options.” In the next screen that comes up, click on “Save” in the column at the left. In the panel that appears at the right, you’ll notice an option called “Save Files in this format,” with a drop-down list of choices next to it. Display the list of choices by clicking on the arrow and select the format that corresponds to Office 2003. Then, click OK at the bottom of the window. For instance, in Word 2007, the format you want is called “Word 97-2003 Document (*.doc).”

The other option is to enable Office 2003 to handle the new formats, by downloading a free “Compatibility Pack” from the company’s “Download Center,” at www.microsoft.com/downloads. You’ll find it listed there under “Popular Downloads.”

When will Google offer its much-discussed cellphone for sale?

Google says it isn’t planning to build or sell mobile phones. Instead, it is developing a cellphone operating system, or software platform, called Android. And it has assembled an alliance of companies, including phone makers and cellular network providers, to create phones based on this new platform. This group is called the Open Handset Alliance. In addition, since Android will be so-called “open source” software, Google expects numerous developers around the world, large and small, to modify the operating system and create programs that will run on it.

If all goes according to plan, Google says it expects to see many different Android-based cellphones and other mobile devices, from a variety of manufacturers and carriers, in various designs and with differing functionality and capabilities. Some may be larger-screen “smart phones,” similar to an iPhone or BlackBerry. Others might be smaller, simpler phones. Still others might fall somewhere between an iPhone and a small laptop.

Google officials say they expect the first Android devices to be available later this year.

After reading your Jan. 3 column, I looked unsuccessfully for a Home and Student version of Office for Mac 2004. Does such a version exist?

In the 2004 release of Microsoft Office for the Mac, this low-priced version had a different name: the Student and Teacher edition. Microsoft presumably changed the name of this $150 product to the Home and Student edition in both Office 2007 for Windows and Office 2008 for the Mac, because, while it was technically limited for sale to families containing students or teachers, no proof was required and it was widely purchased by consumers in general.

However, there’s a big difference between the latest Windows and Mac versions of the Home and Student edition. In the Mac version, it includes Word, Excel, PowerPoint and Entourage, Microsoft’s equivalent of Outlook on the Mac, which, like Outlook, includes email, calendar and contact functions. But the new Windows version now omits Outlook, and instead substitutes OneNote, a note-taking and information organizing program that is far less commonly used. So, Windows users must spend much more money to get a version of Office that includes Word, Excel, PowerPoint and Outlook.

Is there a way to back up Microsoft Outlook Express emails, particularly Inbox items?

Outlook Express stores your emails in database files, with all the messages in each of your mail folders lumped into a single such file. These files can be backed up, or copied, onto other hard disks, or storage media.

The email data files are usually buried in obscure subfolders in Windows. But you can locate them by clicking on the Tools menu, then Options. This will open a tabbed window. In this window, click on the tab called Maintenance, then the button called Store Folder. This will generally give you a long, complicated path to the folder.

Next, copy this path by selecting it and pressing Control and C. Then, click on the Start menu, select “Run…”, and then press Control and V and then click OK. This should open the folder that contains your email. The inbox is contained in a file called Inbox.dbx. This is the file you will want to back up. If you want to back up other folders, such as the Sent mail folder, you will find them along with the inbox file, with the same “.dbx” suffix.

Some backup programs may automate this process by simply allowing you to designate that you want to back up your Outlook Express emails. There are even some programs specially designed to back up Outlook Express messages. You can find some of these by simply performing a Web search on “backup Outlook Express.”

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions about laptops sans serial ports, repartitioning hard disks and expanding storage capacity.

If you have a question, send it to me at mossberg@wsj.com, and I may select it to be answered here in Mossberg’s Mailbox.

Because of the volume of e-mail I receive, I can’t routinely answer individual questions by e-mail, or consult on individual problems or purchasing decisions. I read all questions I receive and select three each week to answer in the column.

I notice that Dell sells some laptops without parallel and serial ports. Is it OK to buy a laptop without them?

For the vast majority of average consumers, the answer is yes. Parallel and serial ports were, for years, the primary way to connect Windows computers to printers, scanners and other devices. But they have been replaced in the past five years by faster and more flexible USB ports, and, to a lesser extent, by FireWire, or 1394, ports.

Some corporate-computer departments still maintain equipment that uses the archaic parallel and serial ports, which is why IBM, Dell and others include such ports on some laptops aimed at the big-business market. But the only consumers who need these ports are the tiny minority that are still trying to use ancient printers or other peripherals.

I want to repartition my hard disk to transfer capacity from the D drive, which is empty, to the C drive, which is full. When I called tech support, I was told that the only way to do this is to perform a system restore, which includes reinstalling all the software on my system. Is there an easier way?

Yes. You can use a very handy program called Norton PartitionMagic, which can change your hard-disk partitions without disturbing or deleting any of your installed software or data files. The program is made by Symantec, and costs about $70. More information is at www.symantec.com/partitionmagic.

I’ve been dabbling in creating home videos with iMovie and iDVD on my iMac. I find I need more disk space to store all my clips and such. Is there a way to expand the hard-disk storage?

You might be able to bring the computer to a dealer and have a larger hard disk installed internally, and your data transferred. But a simpler solution would be to buy an external hard disk that hooks up to the iMac through its FireWire or USB port.

In most cases, these drives just plug in and work immediately, without any software installation or configuration. You can buy these external drives at most computer stores, physical and online. They vary widely in capacity and price.
