One of my biggest reasons for not embracing ebooks earlier, and I still haven't quite yet. It's nice that textbook manufacturers are making their textbooks available in an ebook format, but some of the books I buy (particularly for computer science) I intend to keep, as reference material. Being limited to reading it for 365 days means that I'm unable to do so. I was looking at the Operating systems book (an inside out approach, I think is the sub-title), and it was $80. Why would I continue spending $80/year in order to have a book? They claim I save $75, but that $75 will pay for itself in my ability to keep using my book that I purchased.

I suppose enTourage doesn't want to/can't/won't push for DRM free accessibility?
