If you caught our review of Thumb Keyboard last month, you'll know the gist of this clever keyboard app that aims to make two-thumbed typing a breeze. It's a novel (and potentially very useful) tool for a phone, but with recent updates that have accentuated the tablet layouts, this has now become my keyboard of choice on large tablet screens, and is a potential game-changer in the new slate arena.

On phones, trace keyboards like Swype and SlideIt are extremely hard to beat in the speed department (world texting records seem to be broken on a regular basis with Swype), but on the wider tablet screen, tracing suddenly becomes much less convenient.
