From what I can tell, there are no legal textbooks available for the Kindle. I would buy one in a heartbeat, and probably pay more for the books if I could get them electronically like that. The only "paperless" option I've been able to come up with involves buying a Kindle or Sony eBook that supports PDFs, cutting the textbooks and scanning them to PDF. But from what I've seen, PDF's aren't completely clear on any of the eBooks, and the process of scanning 4 1000 page books would be pretty brutal. You'd either have to have access to a high speed, duplex scanner or pay Kinkos to do it, which I'm certain would cost a small fortune. I'm sure it'll be a few years before the textbook publishers finally realize there is a market for this kind of stuff, or figure out how to profit from it.
