I wonder how this will fit to people who type on a keyboard 10-12 hours a day. The advantage with virtual keyboard is the infinite reconfiguration capabilities w.r.t. repositioning of keys for reasons of ergonomics. For the same reasons, though, keyboards designed with ergonomics in mind (e.g. http://en.wikipedia.org/wiki/Ergonomic_keyboard http://en.wikipedia.org/wiki/Ergonomic_keyboard) can't be replicated because of size and three-dimensional profile.
