I think it should replace all the textbooks in the university. It is incredible the amount of dead trees that goes into making all those textbooks that are in turn are very difficult to transport and use. Perhaps textbook social learning app?

I think iPad fell short with its textbook software - can someone make a platform. There is the issue of expensive and profitable dead tree textbooks though.
