The N810 is an excellent mobile Web device thanks to a fantastic browser and a great display. However, despite all its strengths there are plenty of flaws.

The iPAQ's VGA display alone makes it an excellent PDA while the dual-storage slots make it easy to upgrade memory. This is a solid, high-end device for professionals.

While for many users a PDA is a superfluous device these days, for those that want an extremely quick, fully featured handheld PC then HP's iPAQ 112 is towards the top of the pack.

While expensive, the LifeDrive is an excellent PDA packed full of features, and it would surely satisfy even the most demanding of business users.

The Tungsten T5 will appeal to people who want a Palm-based business handheld that can double as a portable storage device.

Considering the many features packed into its diminutive chassis and its snappy performance, the Zire 72 is a bargain.

The low-cost Palm Tungsten E2 is a comfortable entry level model for business users.

Solid, but not outstanding, the HP iPAQ hx2190 offers mobile users some key improvements sure to make life easier.

Stylish, small and simple to use - there's nothing wrong with the Z22. And there's plenty to like about that price, too. If you want a PDA, you'll struggle to match these levels of quality and value.

The ASUS MyPal A730 packs a lot of features into an attractive package, but it could make better use of some of them.

Not ideal for personal usage, the MC50 is designed to facilitate mobile computing offering PDA features in a rugged design. While the unit is solidly built and includes native Wi-Fi, the presence of a scanner adds significantly to the price.
