PDA Buying Guide

Also known as a handheld computer, a PDA (Personal Digital Assistant) is great compliment to your existing computer, designed to fit in the palm of your hand and offer a range of scheduling, internet and computing functions.

Essentially a PDA is defined by what you can do with it. For some, a PDA is a powerful electronic organiser, while for others it is primarily a communications device. However, for most users it is a combination of computer, word processor, telephone and internet browser.

There is a wide range of PDAs on the market, to suit most budgets and needs. Here are some useful hints and tips for things to consider when choosing a PDA.

Features to Look for When You Choose a PDA

Today's PDAs are as powerful as the laptop computers of 5 years ago, and typically include a touch-sensitive screen for input, a memory card slot, and an IrDA port and/or WiFi and Bluetooth for connectivity.

Different models of PDA have different features and specifications, so check the product descriptions carefully to make sure that any model that you're considering will suit your needs.

Key features and specifications look out for when comparing PDAs include:

Touch-screen - A touch-screen can be used to view documents and web pages, and also for input, either through a virtual keyboard or word/letter recognition. Some PDAs come with a stylus that can be unclipped and used to either select letters from a keyboard on the screen, or to write words on the screen that can be recognised by the PDA. Some models of PDA use a finger sensitive screen, dispensing with the need for a stylus.
Keyboard - PDAs can come with a typewriter-style keyboard as well as a touch screen. Larger keyboards can even be wirelessly connected to the PDA, making it easy to type large documents.
Synchronisation - One of the main functions of a PDA is to work alongside your computer, making sure that work on each device is synchronised and up to date. Ultimately, for important data like contact details, schedules and email, the PDA will contain the same information as your computer. Some users prefer to update details on their PC, so they've automatically got the same documents and data on their PDA when they are away from their computer.
Software - Many popular software applications such as Windows-based programmes like Word and Excel are available for PDAs. Make sure that the software you choose for your PDA can be synchronised with your computer.
Operating System - There are two main operating systems for PDAs - Palm OS and Windows Mobile. Both are versatile and are compatible with a range of both PCs and Macs, but if you have a Mac, one to consider in the future is Apple's new operating system for PDAs.
Memory - If you want to store music files and large amounts of documents and data on your PDA, you should consider buying a model with at least 128MB of memory. If you're on a budget, it's worth noting that PDAs with a lower amount of memory are significantly cheaper.
Connectivity - PDAs can use different methods to connect to other devices such as computers and other PDAs. A popular method of connection is via IrDA, an infrared port. Increasingly, PDAs are using WiFi and Bluetooth for connectivity, for wireless connections to computers, other PDAs and the internet.
Web access - A PDA can access the internet in different ways, either showing pages that you have stored on your computer or wirelessly using WiFi.
Battery - PDAs can come with rechargeable or standard batteries.
Weight - PDAs are typically lightweight, weighing from around 90 grams to 180 grams.
Expansion Slots - Some models of PDA have expansion slots, enabling you to connect a digital camera, extra memory or accessories to your PDA.
Accessories - There are a range of accessories available for PDAs including cradles for synching a PDA with a computer, keyboards for easier typing, audio cables for connecting your PDA to an MP3 player, and mount kits for securing your PDA to a dashboard or desktop.

Do I Need to Buy an Extended PDA Warranty?

Before choosing your PDA it's worth looking at the warranty available for it. A warranty covers you for repairs to your PDA or a replacement under certain conditions. Warranties can vary between manufacturer and retailer, but by browsing online you can easily compare them.

Set a limit on the amount of money that you're prepared to spend on a PDA. However, by shopping around online, comparing prices between online retailers and taking advantage of special offers or discounts, you could find a great deal on a better model of PDA than your budget would normally allow.
