I think he was fine at communicating and not terrible to listen to. I just didn't find the talk that interesting or cover anything I didn't already know about quantum computing theory. I wish it did, because there's much I don't understand.

He has an excellent book, Quantum Computing Since Democritus. That's a good resource.

Don't you expect a bit too much from 15-minute-long TED talk? Actually I think it was more informative(and definitely clearer) than a lecture on that subject I had at the university.
