Because the introduction of the new iPad is not coming with a new version of the operating system with radically new functions, few updated media apps are appearing in the App Store prior to tomorrow's launch.
The big reason of the update is that the app is "optimized for the new iPad's Retina Display", but there are other changes, as well.
The iPad app also adds in-app word definitions (for those who can never understand Tom Friedman), and article syncing improvements.
Another app that was just updated may be even more important to some owners: Amazon.com has pushed out an update to its Kindle app has is also claiming to have been optimized for the new iPad's higher resolution display.
Several iPad reviews today have mentioned that books are definitely a joy to read on the iPad and that Apple's iBooks takes advantage of this – mentioning that Amazon's Kindle app does not.
Well, I don't think Amazon liked the idea of their app not being "Retina" ready, and they've done something about that today.
(Apps from Amazon appear in Apple's App Store under the seller name of AMZN Mobile LLC.)
