I'm considering going the digital route this year with my textbooks if possible because carrying around a bunch of heavy textbooks is a pain. Has anyone successfully used one of these machines for all of their textbooks? How has it worked out and have the teachers and other seemed to go along with it? I'm just looking for some real world stories before going out and spending the money. I'm probably going to go with either kindle or nook though since I don't have enough money for the ipad right now unfortunately but any stories or information are helpful.
