In fact in Japan atm I use a starboard (basicly a large projector with touch capabilities), in my classroom. If things like this became more common, I'm sure education could be shaken up a lot.
I watched some classes on MIT OpenCourseWare and was blown by the fact that they use chalk boards (!). I mean, one of the best universities in the world use the same tools as mine: a teacher, chairs and a chalk board. Don't that make us think about how important is the culture, the environment of those famous institutions. It's not about tools, it's all about people.
It is an excellent medium to teach a class withe.
