The Future of Electronic Texbooks

Stephen posts about a Bill Gates quote in which Bill claims students will all be using electronic textbooks within 4-5 years.  Stephen thinks not, at least not that quickly, and I agree.  Just too many different formats and DRM non-standards out there to make this work even within 5 years, IMHO.  I can see some textbooks being available this way, but not all.  I hope I’m wrong though.  🙂
