ya, i have been doing that for years now. I am using my x51v to store about 4 books. I don't have to be carrying 50 lbs of books with me. Currently I have my genetics biology book (80 mb), calculus book (20mb) with solution manual (80mb), and my physics book (100mb) on my axim. The rest of my textbooks that I no longer need are archieved away. The text search ability is helpful in locating key words instead of using the index. you can get good college ebooks on --REMOVED LINK--
