OMG i pay about 200 to 500 a semester for books and the prises keep going up every year, i'm sick of paying so much. When i can i get the code for the book and order it on amazon or something. I think this is a great idea, most of the kids at my school could certainly use something this. How typical of the instructors to think this is somehow undignified, elitist dingdongs. I'd just cut the adds out of the books anyway
I like the PDF idea too, but not everyone has a computer and you can't take a computer into classrooms, unless it's a notebook computer, but that's more expensive than just buying books. I don't really see this as being a possibility.
