On the question of using a small screen for textbooks, The Apple Blog writes:

People might be quick to note that the iPhone’s small screen is hardly ideal for working with text books, most of which have larger than average publishing formats, which is why Amazon went about creating the Kindle DX in the first place. CourseSmart isn’t trying to sell people on the idea of using the pocket device as a straight-up substitute for all other learning aids, though. The app is designed to supplement its existing catalogue of e-textbooks on other platforms, not replace it entirely.
