Update: Impressions after the break!
The alpha version of the SwiftKey tablet interface is pretty darn impressive from where we stand. Though we did sometimes found ourselves reaching for a B with our left thumb and the landscape interface doesn't have a full pane of symbols, the horizontal split makes for pretty reasonable virtual keyboarding while holding the tablet nice and stable in the palms of both hands. What's more, SwiftKey's three-button word prediction system makes things speedier yet: You can immediately enter the best guess with a tap of the spacebar, the runner-up using your right thumb, or tell the interface no, you really did intend to type "vacuum" with your left. (If you just keep tapping spacebar, you can come up with some hilarious auto-generated sentences.)
TouchType plans to release a beta version of the software shortly after Mobile World Congress this month, and expect to finalize things by mid-April as a guess, with plans to shrink the keys slightly for more comfortable thumb entry and add symbols before then.
