Three things to consider in PDAs

It's back-to-campus time. Instead of splurging on a new laptop or desktop computer, a handheld computer might fit the bill.

At first glance, it's easy to dismiss handhelds, also known as personal digital assistants (PDAs). After all, most cell phones allow you to store phone numbers, schedule appointments and even surf the Web. But most of those functions are rudimentary, and a handheld can deliver a richer, easier-to-use experience.

When shopping for a handheld, the variety of models can be overwhelming. Narrow your focus by looking at three major points:

1. Operating systems. There are two major operating systems — Palm and Windows Mobile (formerly called Pocket PC). There are other proprietary systems, but they have a small market share.

Previously, Palm and Windows were miles apart. Palm was best known for ease-of-use in inexpensive handhelds. Windows Mobile systems were more expensive but more powerful — easily handling multimedia applications. You can discard these stereotypes because they no longer apply.

The newest versions of both operating systems are roughly equal in many ways, including ease of use, but two factors — data input and software — distinguish them.

To input data on the go, both types of PDAs use a penlike stylus and software that recognizes your handwriting. You enter names, addresses and notes in a special area of the screen using the stylus, and it's converted to text.

Palm devices use a handwriting recognition program called Graffiti 2. It takes a bit to learn, but it's easier to master than the original Graffiti program.

Windows Mobile offers more versatility with three handwriting recognition programs. Block Recognizer is similar to the original Graffiti program — a difficult method for the uninitiated. Letter Recognizer is similar to Graffiti 2. Transcriber allows you to print characters or write in cursive letters, and it works well.

Because Palm handhelds once dominated the market, more software is available for them than for Windows Mobile devices, but you'll find solid programs in all major categories for both types of PDAs.

2. Prices. Handhelds begin at $99 and approach $1,000. But the best deals begin at $300.

There are few models under $150. At this price, you'll get a machine that is good for organizing homework assignments and taking notes.

At $300, you'll find units with powerful processors, built-in wireless functionality and color screens. Built-in Wi-Fi (802.11b) is a big plus where wireless networks are prevalent.

3. Some bells and whistles add value. Many models have built-in microphones that allow you to record lectures. Once recorded, you can transfer them to a PC in common sound formats for archiving.

Handhelds generally have 1.2- or 1.3-megapixel cameras. These aren't the best, but they're better than most camera phones.

To make the most of your PDA, keep it in a protective case ($20 to $50), buy memory expansion cards ($20 to $100). Finally, think about adding a compact, foldable keyboard, which can make typing easier ($40 to $100).
