From iBIZ Technology Corp., Phoenix (www.ibizpda.com), the device uses no moving parts to project a full-size keyboard image onto a flat surface. Laser and infrared technology pinpoint the correct letter to type according to location coordinates. The projector weighs 2 oz and is the size of a disposable cigarette lighter. A lithium-ion battery powers it for 3 to 4 hr. The keyboard is compatible with Win98/2000/XP, as well as most PDAs using Palm or Pocket PC operating systems.
