iBooks 2 hands-on: Apple’s reinvented textbook | The Verge
As for Life on Earth itself, it runs extremely well even on the original iPad we tested it on. Movies load quickly, page turns are smooth, and embedded animations work without a hitch. Images are particularly engaging, as most go full-screen with a tap, and also contain a number of other related images to swipe through as well. The download process was slightly painful, but that could be due to a large number of people hitting Apple’s servers all at once.
