2. Physical Properties/Technology/Power Requirements

I heard the VKB was about the size of a pack of Tic-Tacs. However, it is much bigger, measuring 3"x1"x1." This isn’t that "space-saving," as it’s not that compact and is thick. I found carrying around a Belkin foldable to be just as convenient, since you can slip it in your pocket as it is less thick. The 6315’s included thumb board is just as small or smaller as the VKB. You need a fairly large flat surface to accommodate the VKB’s projection area which isn’t a requirement for a thumboard and less so, a foldable.

The VKB is sturdily constructed and comes with a leather pouch. A red laser projecting the keyboard beams from the top with the power supply at the lower left and reset settings on the bottom right. Latency settings allow for auto-shutoff if unused; if the unit is picked up, a sensor on the bottom automatically powers it down. The extended projection window/keyboard size was 3.5" x 11" with the VKB approximately 7.5" back from the opening projection line. In contrast, the space profile for the Belkin foldable was 3 5/8" x 10.5" and the thumb board simply attached to the PDA.

The model I received shipped with an internal rechargeable battery and included an AC adapter/North American pin converter. Battery life was very good. I found that it took little time to fully recharge and that the battery held a charge well. I had left the keyboard in my car for over a month and found it near the charge it was left at. The total typing time I experienced with my unit was about three hours.
