Regarding the other commenters baring their teeth to attack the UI, how in the world is that in any way useful or productive? Just yesterday we were upvoting Collison's top questions, one of which was that the book needs to be reinvented for learning. In fact it's still on the homepage with 971 points[1]. I'm not saying this particular presentation is correct or the answer, but I'm thrilled to see attempts being made and can't imagine why you would be hostile toward someone for (and thus discourage others from) making the attempt to try something new.

On the one hand, we talk about getting something launched and out there, and on the other we get on our high horse and complain that it isn't functional on every platform and screen size? I feel strongly that this should be a supportive environment for new and interesting attempts (and thus uncertain and perhaps buggy ones).
