"The newly designed books are graphical, interactive, and make use of features like 3D imaging, embedded video, and multitouch gestures. The company seems to be taking cues from several applications which have been available for the iPad such as Frog Dissection and Solar System, both of which Apple called out at the event. They're also beefing up the notetaking functionality of the iPad, and the books will be available for purchase in the iBookstore directly. Apple has also announced that, at least for the titles it's making available today, the price will be $14.99, and it's just announced its first series of publishing partners, which includes Houghton Mifflin Harcourt, McGraw-Hill, and Pearson."
Okay, but how about some law casebooks? I've been lugging those damned things around for 35 years! (I'm complaining, but I've gotten these heavy tomes free for the last 28 years. My students pay 10 times $14.99 for the book I make them buy. And they have to shell out another $30 for the supplement to bring it up to date, which would be a non-issue for an ebook. And I'm talking about books that are mostly the text of court cases, which are in the public domain.)
