The Keystick is a foldable, compact, portable keyboard that is designed for folks that fear a little bacterial contamination from the keyboards of public computers.
It is just a concept for now, and while it does look cool, one definitely questions whether marketing the cleanliness of a product is more useful than promoting its portability. Japan has more than its fair share of germophobes, but even here, I think it will be a tough sell. It looks cool though. [Yanko via TFTS]
