This 65-key Bluetooth keyboard is a great tool for those who need to enter more than a few characters into a PDA. The keys are a little smaller than a full-size keyboard, but this is meant to be a fold-up travel companion to a PDA, and so a full-size keyboard would be impractical. Wireless is a major benefit, and battery life is reported as 90 hours continuous use or 160 hours standby on 2 (included) AAA batteries - plenty of power. Setup requires a quick driver install on your Palm, Pocket PC or Symbian and comes as a self-installing 40K .prc file. With an included case, this makes sense for anyone who's ever been frustrated at data entry with a handheld.
