Apple introduced a number of new products and initiatives at its event in New York this morning, including textbook support in iBooks 2, the iBooks Author content creation tool, and a new iTunes U app for iOS. If our hands-on impressions and liveblog didn't leave you sated, Apple has now posted video of the event itself. It's available for streaming on the company's website, or if you'd rather have a copy for safekeeping, you can download it through iTunes as one of Apple's video podcasts.
