i actually played with one of those not too long ago. it's pretty slick, but really just as a geek toy and not for functionality. it needs to be on a completely flat surface for all the keys to work. and even then, you're just tapping on a table, there's no feedback like a keyboard would give. also, depending on how you hold your hands, if you block the sensor some of the keys won't register. don't expect to use this on a magazine or in your car, you'll need a completely flat table or something rigid.

a very interesting bit of technology, but it still has a little bit to go before it can be used to replace a real keyboard (though for a PPC device it's not terrible).
