Mr. Christensen, a well known professor at Harvard Business School, was being interviewed by Walt Mossberg in this video.
There are 3 parts to this video, talking about innovation in technology, healthcare, and education. I didn't quite agree with Christensen's prediction that Nokia will win the battle in building mobile devices. He seemed to have used his model on Nokia and Apple without taking into account the fundamental different natures of the two companies.
Having said that, I did feel that his talk on healthcare and education interesting. My question is how can we build technology systems that really help kids to learn in their own style, in a way that really maximizes the value of technology and human teachers?
