Down on VKB's Bluetooth Virtual Keyboard
CNET completely trashes VKB's Bluetooth Virtual Keyboard, or BTVKB, which is essentially a Bluetooth-enabled version (duh) of those projected laser keyboards which have been kicking around for about a year or so. Besides not being able to get it to work with a Pocket PC (they were eventually able to pair it with a Zire 72), they found that the lack of tactile buttons made typing accurately a little rough. Not to mention what tapping away on a flat surface does for your hands. Try tapping your fingers on your desk for a fifteen or twenty minues and see how you feel—those keys in your keyboard are spring-loaded for a reason.
