Firstoff, thats a very well-done video. Inspired employee with a 5dmk2 or professional? The UI looks pretty nice, but of course Ill need to actually use it before I make that. And props to them for keeping it under wraps successfully for so long.
It's not activated for me yet, but it looks cool. They learnt from twitpic and long-tweets :) I've never wanted to use third party applications for that before
