Back when this was first unveiled, I really, really wanted it. Then it suffered delays, and I lost interest in desktop computing. (I love the concept of notebooks, even if I’m on a Dell right now...) Then the price skyrocketed and the production numbers plummeted.
It’s best to wait until someone rips this off (Logitech?) and mass-produces a cheaper version.
Old electrics (circa 1960s) had fantastic control over key pressure and you could type for hours without feeling like you'd been drumming your fingers into a steel plate.
I have a design that uses a laser array to track finger twitches so that no keyboard at all is needed.
You want qwerty you get qwerty but you can also get your favorite game controller configuration ~ just run the trace and track program.
It should be just as easy to do a one-handed virtual keyboard operation with this design.
All I need is several hundred thousands of dollars for R&D.
