I always mind of expected that someday we'd come up with something more sensible than a miniature Qwerty keyboard for text input on a phone. Something not unlike Swype (or any number of the other alternative keyboards out there) but with an interface which does away with the keyboard metaphor (note that Swype is the only one so far to catch on in any way).

(Also note that voice recognition doesn't count, as to compete with a keyboard your input mechanism has to be discreet)
