First its amazing that this is a better UI than anything RIM has put out to date. Light years ahead of anything they've put out there. ANYTHING. And that includes the soon to be released OS7.
Second, his presentation is better than anything RIM has put out to date. ANYTHING. Hope this kid can do something with the Theme Maker 7.0. Of course RIM would never open up enough APIs too do half of this. Honestly, its 7 months into 2011 and RIM still does not even have a native full screen caller ID or a decent API for developing one. Though many have tried.
