<p>I'm wondering... has anyone ever tried using a pdf version of a textbook and downloading it to their iPad? Does it work on iPad so that you can enter in a page you want to go to and it does so? I know this doesn't replace owning the textbook but just for when I don't want to carry it around with me.</p>
<p>Amazon is introducing a textbook rental/purchase program. You can use the kindle iPad app or the one for you laptop.</p>
