Happily, though, Synaptics says that's something it's able to fine-tune, depending on whether a PC maker wants a firmer keyboard or something a bit softer. (We say the market has enough flat, lifeless Ultrabook keyboards, but that's just us.) In any case, we hope to test a more polished keyboard sometime later -- one that has all those additional touch-sensitive features enabled.
Second, newer approaches to CAPTCHA have been developed that try a different approach to a Turing test by asking users to perform operations through input devices, like a keyboard or mouse.
