I would have killed for an ebook option for my textbooks. I was really sick the last year I attended college. I used a cane, and could barely carry my backpack. A Kindle, or the like, with all my textbooks loaded on it would have made my life easier. Even now that I am healthy, I would rather have them all loaded on a ereader of some sort, than hauling the books to class.
I just don't like carrying books around, though.
