Not sold on reading on the iPhone? Give it a shot for free with Stanza. In addition to including magazine and newspaper content, the program links to the massive Project Gutenburg, which maintains free copies of more than 30,000 classic books that have fallen into the public domain, meaning their copyright has expired. That includes a lot of the reading list in a typical class: the full works of Shakespeare, Dickens, Nietzsche and a diverse slate of classic authors. Stanza keeps track of your progress and lets you adjust the text size to avoid eyestrain. (Stanza, free)
