While I am envious that upcoming generations will not know the absolute joy of lugging around Chemistry, Physics and Math tombs, I am a little weary that this plan will eliminate the used text book market. I, for one, certainly bought more than one used textbook for less than 50% of the price of a new text. I also had professors recommend going to the off-campus, unaffiliated book store for used texts rather than going to the for-profit on-campus book store in the student union.
