NOW IF ONLY THE BIG TEXTBOOK PUBLISHERS WOULD GO THAT WAY!
Yes, you are right, but we are not there yet. I do see that we may get a group of standard executable platforms BEFORE we get a standard file format.
I think once reasonably large screens are commonplace for readers that PDF will become a more viable format for textbooks. I've downloaded a couple of O'Reilly eBooks, they supply them in ePub or PDF, and the PDF provides a superior layout.
