If you are wiling to sacrifice storage space and power for a low price point, then this is the PDA for you.

Performing well in a number of areas, HP's iPAQ 312 is a bit of a jack of all trades. While the media playback features are a bit of a gimmick, the GPS is robust and the Bluetooth hands-free functions well, making this a solid choice for users who have yet to jump on the GPS bandwagon.

A PDA dressed in a portable media player's clothing, the rx4540 is an attractive device that is equally good for productivity and mobile entertainment.

This PDA is fast, powerful, and equipped with both Bluetooth and Wi-Fi, but the biometric fingerprint reader doesn't work as well as it should.

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

The MyPal A696's GPS is handy, but the navigational experience isn't as satisfying or complete as the multitude of dedicated portable units on the market. What remains is a solid, yet unremarkable PDA.

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

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.
