It's hard to get excited about textbooks, until you see something like this: Apple just made the notecards obsolete forever. No more index cards, no more boxes — no paper. iBooks 2 turns your reading habits into instant study help.
With the new iBooks 2 textbooks, anything you search or highlight will automatically generate a study card to be used later. Reading about the Franco-Prussian War, or genetics? Anything you highlight, look up, or take a note on becomes a card for reference and self-quizzing.
