TMo2, it's a good point. I agree that the cost of e-texts needs to come down significantly... supposedly, textbook publishers blame their high costs on relatively small print runs, so going digital should result in significantly lower costs. I say "should." "Supposedly." A lot of loaded words in there.
There has been talk of the possibility of absorbing textbook costs into tuition fees. This would mean the schools would essentially pay for the books, short-circuiting the present system where professors often get kick-backs for requiring certain texts... at which point the schools might take a more decisive hand in working with publishers to reduce costs. Either way, it should reduce student costs, and make e-texts more attractive to students (as opposed to paying more for printed texts).
