I'm still digging through all of Apple's announcements yesterday, and I found another one.
Among the many features of iOS 5 is one that could be rather interesting. Airplay is going to be expanded from just videos to include support for all IOS apps. (Airplay is the tech that lets you send video from an iPhone or iPad to an Apple TV. ) This means that you'll be able to open the Kindle app on your iPad and then use Apple TV (at right) to show the app on your television.
I;m not sure how much good it would do for text, but picture books will probably benefit from this new feature. And I'm looking forward to seeing what this does to games.
