More to it than that. The readers, IFAIK, all have proprietary "book stores." Buy a reader, you can only read books for that reader. I don't plan to spring for a reader until I can buy anything and read it.

And the readers do have to take a lot more abuse than, say phones and iPods take today. Certainly more than laptops. They have to go into a jacket pocket.

I do read on screen at home. Other places, I ogle women.
