Emerging briefly with my elderly writer's hat on:
One of the problems with textbooks is that they tend to recycle and regurgitate what the other, older textbooks say. This is not an original statement: Thomas Kuhn made it almost 50 years ago in The Structure of Scientific Revolutions, though he was talking about the absence of real-time physics in the stuff read by physics undergraduates.

Now I will get on with the tale of Bushnell's 'Turtle', which went to sea with a 70 kg clockwork bomb ticking away, a bomb that had to be affixed to a hull before it went off. Definitely not a good reference point for predicting the future, that one.
A small afterthought added in late 2011: I think we haven't even scratched the surface yet on e-books, and I have a few ideas about what we might explore: try clicking this link.
