Just when businessmen and women were getting used to BlackBerry's SureType split-key keyboards, RIM has to go and patent yet another method of inputting text.

Remember Microsoft and their ergonomic split-key angular keyboards? This is that, but smaller. We like what we see, sir. [Cellpassion via MobileWhack]
