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.

A lot of the laptop companies seem to have abandoned the traditional docking station. These docking stations have a large rectangular connector that interconnects with the notebook from the bottom. The newer docking stations seem to be much smaller, with fewer connection options. Is a new trend in docking-station design emerging?

The kind of large, fully equipped docking station you describe was born years ago, when laptops were different. They tended to have smaller screens and hard disks, more-cramped keyboards, weaker batteries, only wired Internet connections, and many fewer ports and connectors.

But the need for such docks has diminished, since modern laptops come with more ports, larger screens and keyboards, better batteries, wireless connections, and more-spacious hard disks. The old-style, more fully equipped docking stations are still available for some laptop models.

I suggest you look around at laptops meant for large businesses, which typically have been the market segment most interested in these accessories.

My daughter was given a Sony laptop. It has a 40-gigabyte hard drive that has two 20-gigabyte partitions. What is the best way, either using software that comes with XP or an after-market program, to remove the partition and then have one 40-gigabyte hard drive again?

I suggest you use a program from Symantec called Norton PartitionMagic, which can either split a hard drive into partitions, or merge partitions into one, without data loss. It can be downloaded from symantec.com/norton/partitionmagic or purchased from various other merchants.

I notice on my iPhone calendar that I can’t get a “week at a glance.” Is there a solution or alternative available?

The only built-in alternative I know of is the calendar’s “list view,” which displays all your appointments in a scrolling list that is organized by day, but not by week.

There is a third-party calendar program for the iPhone called SaiSuke that appears to have a week view, as well as a detailed month view. It costs $9.99 and is meant to sync with Google Calendar. I haven’t tested it, so I can’t say how well it works.

How do I transfer contact and calendar data from the Palm devices at our small company to the new BlackBerrys we are getting?

There are several ways to do it, but I’d suggest using Microsoft Outlook as an intermediary, because both Palms and BlackBerrys can synchronize data with Outlook. So, I would sync your Palms to Outlook, and then sync the BlackBerrys to Outlook on the same computers. The data that had once been on the Palms will now be on the BlackBerrys. No special software is needed for this. Both devices come with built-in software for syncing to Outlook.

I have a quick question related to the new iPhone. I am considering getting my daughter one, but I would like to place some restrictions on whom she can call and text and from whom she can receive calls and text messages. Is this possible?

The new iPhone operating system does include some parental controls. But these mainly involve Internet content and don’t permit the setting of limits on calls and text messages. As far as I know, there isn’t a third-party program that permits such limits, either.

So, you’d be forced to pay AT&T $4.99 a month for a service called Smart Limits. It lets parents control which numbers the phone can call or text, and from which numbers it can receive calls and texts. It also allows a variety of limits and controls to be set.

My Windows hard disk has been partitioned into four small volumes. Now, I want to combine them into one larger volume. What is the easiest way to do this?

I suggest using a program called Norton Partition Magic from Symantec.

I have a 3-year-old PC, which has a single physical hard disk divided into a small C drive that is almost full and a larger D drive that has lots of empty space. I know I can move stuff from C to D, but how can I either merge these hard drives or somehow make D the automatic destination for files I download?

You can merge the drives into one larger C drive, or redistribute space between them, by using what’s called a disk-partitioning utility — a program that rearranges the space on the hard disk without erasing your files. One I have tested and found that works well is called Partition Magic and is sold by Symantec.

Short of doing that, you can change the settings in programs you use to download or save files so that they store the files on your roomier D drive. Not every program has such a setting, but many do. These settings are usually found in the options or preferences sections of the software. For instance, in the latest version of the Firefox Web browser, go to the Tools menu, select “Options,” and, under “Main,” in the Downloads section, you can specify a folder on your D drive where it says “Save files to.”

In your review of the Amazon Kindle e-book reader, you praised its ease of downloading books, but criticized the hardware design. You seemed to prefer the design of the Sony Reader, which costs $100 less, but said it offers fewer books. If you had to choose between them, which would you pick?

Neither is a compelling product. However, putting aside price as an issue, I would choose the Kindle, despite its design problems. The Sony is slimmer, sturdier and, unlike the Kindle, it isn’t prone to accidental button-pushing. But Amazon’s device can download books directly, without the need for a PC. Sony’s can’t. And Kindle’s online catalog of compatible titles is 90,000 books, more than triple the number Sony offers.

Unless you absolutely crave an e-book reader now, I’d suggest waiting for a system that’s better than either. However, if you’re going to invest $300 or $400 now in a device to read electronic books, you would likely want the one with the widest selection of titles and the quickest, easiest downloading process. And that’s the Kindle.

I use Outlook Express for my email. I have been getting a lot of offensive junk mail I’d rather not even view for a moment. Is there a way to delete incoming mail in Outlook Express without having to first view the contents?

You can avoid automatically viewing the contents of your email in Outlook Express, and many other email programs, by turning off the preview feature. In Outlook Express, click on the View menu, then select “Layout…”, and uncheck “Show Preview Pane.” Then, click OK. After that, you will have to manually open each message to view its contents.

However, you may have to open some emails anyway in order to decide whether to delete them, since spammers often use deceptive sender names and subject lines that make it hard to decide if they are worthy of deletion. So, you might consider installing an antispam program.

I currently spend about $50 to $60 per year for Norton Security software. Is this necessary when Windows XP has its own security built into the operating system?

Windows XP doesn’t include antivirus or antispyware programs, so you definitely need some sort of add-on security software. If you don’t want to pay for it, there are free alternatives available.

How do we determine when to purchase a new PC? Our current Dell is about five years old. I’m feeling a little worried because I have my music and photos on the computer and don’t want to lose them.

There’s no universal answer to your question. In general, I don’t believe people should replace computers that are working well for them just because they reach a certain age. On the other hand, five years is pretty old for a PC. At that age, the odds increase that the hard disk may develop problems, and that newer versions of the software you like will require hardware upgrades that may cost more than you want to invest in an older machine.

Assuming your Dell is working fine, that you aren’t a power user, and that your music and photo activities are simple and basic, there’s probably no urgent need to replace the PC. But, to assuage your concern about “losing” your pictures and music, you might back up those precious files to an external hard disk or an online backup service.

Last week, you compared the start-up time of Windows Vista to Apple’s new Leopard operating system, and found Vista to be much slower. But you used different laptops for each. What would the numbers be on the same Macintosh running the two operating systems?

I ran the tests again on a single computer, a fairly new Apple iMac, which can be started up, and restarted, in either Vista or Leopard. I used the Mac’s Boot Camp feature, in which only one operating system is running at a time, has its own dedicated portion of the hard disk and fully controls the hardware. The machine uses an Intel processor and other key components commonly found on Windows machines, and runs Windows just like a Dell or any standard Windows PC, without any involvement from the Mac operating system.

This Vista installation doesn’t include any of the speed-robbing trial software commonly included by PC makers, though it does have security software from Symantec. However, the test results were very similar — Leopard started and restarted much more quickly than Vista did.

In this simple test, I timed both operating systems from a cold start and a restart until the computer was fully ready for operation, with the hard disk quiet and the network connection established. The cold start, beginning with the computer completely off, took Leopard 46 seconds, but took Vista one minute and 42 seconds. A restart, beginning with the computer running an email program, the Firefox Web browser, and Microsoft Word, took one minute and two seconds for Leopard, and three minutes and 17 seconds for Vista.
