Credit where it's due - at least, I've not seen it before - that keyboard is genius. Sadly I don't want it, but from a pure technology perspective, I watched the video and marveled at the fact that the keyboard was able to act as a large touchpad on the bottom of the phone, meaning that you could select autocomplete entries without having to "leave" the keyboard, and you could select text without your finger being in the way.
So there's the positive - I think that's really smart. Better than a touch keyboard? I guess they're hoping it is, but I'm not so sure. The fact that the keys area aligned perfectly rather than offset like a regular keyboard would probably drive me mad in short order. But a hearty bravo for innovation in keyboards - I like to see that.
Beyond that, sadly, I see BB as a company drowning in its own irrelevance. It had a captive market for years because of the push mail capability and physical keyboards. Now the smartphones have very usable touch keyboards, and they all have push mail capability. Take those away and, IMO, BB has very little left to offer, and such a small ecosystem that there's nothing to pull me in.
