Seven Things to Consider When Choosing a PDA

In the early days, Personal Digital Assistants (PDAs) were not much more than glorified calculators with the ability to store contact information and brief notes. Now, the line between personal computer and personal digital assistant is blurred thanks to the advanced capabilities of these useful little devices.

There are plenty of makes and models to choose from in the PDA market, and finding the right model to suit an individual's needs can be a dizzying challenge. This Tech Tip will take a look at seven basic things to consider when choosing a PDA in an attempt to help simplify the process.

software

The software on a PDA is capable of running completely independent of your computer, but being able to share files and resources between them is one of the key convenience features. software availability is one issue, but compatibility is another. In general, a PDA will come with one of two operating systems: Palm OS or Microsoft Pocket PC, each with its own very different approaches to running one of these devices.

Palm OS is the modern version of the operating system that was found on some of the first PDAs, Palm Pilots. No longer just a dull, greyscale environment, the Palm OS is a sharp looking operating system with many software titles available (either included, as downloads, or for purchase separately) to do just about anything you would want to do on a PDA.

Microsoft Pocket PC is themed after the familiar Windows operating system, and this similarity gives the millions of Windows users a comfortable environment to work with when transitioning to a PDA. The basic commands are the same, and of all the software titles available for a PDA running Pocket PC, many of them are reduced "pocket" versions of what might be found on a computer such as Microsoft's Word and Excel. Multimedia applications are a strong point of the Pocket PC environment, with many titles developed to make these devices more enjoyable and versatile.

Applications are available for either operating system to do just about the same thing, although specific titles available for one may not be available for the other.

Speed

The speed of the processors in PDAs is picking up, and some older desktop computers are being left in the dust by these little devices. Presently, the bulk of the devices on the market are running at clock speeds of 300 MHz or higher, sometimes much higher. The HP Ipaq HX4700 sports a 624 MHz Intel processor, which is also currently the processor found in the high-end Dell Axim X50v

In general, faster processors can be found in the Pocket PC devices, but that does not mean that Palm OS devices are slow. Many experts would argue that the Palm OS runs more efficiently, and may be able to get by on less system memory, which helps keep the speed comparison competitive.

The applications for PDAs have been optimized to run well with less processing power, less system memory, and to occupy a minimal amount of disk space, so either type of PDA should be able to handle typical tasks well. Speed may be the main concern on a desktop PC, but the focus is a bit different on handheld devices, where other features are definitely more important.

Connectivity

Being able to connect a PDA to a computer or other device may be essential for utilizing all of the features to their full potential. Most now make connectivity to a PC via USB the base form of transferring data to the device, but there are a few wireless protocols that may be available on a PDA to make it even more convenient.

Infrared is a short range protocol that can allow for a PDA to exchange data with another PDA, as well as with a compatible laptop or desktop computer. Many PDAs feature an infrared port, but not all
