So I just installed iTunes 10 and the first thing I noticed is that it actually looks different. New icon and revamped UI, but the real changes are in the support for new devices and Apples new music centric social network ping. Like anything out of Cupertino the interface is elegant and integrates into iTunes perfectly. I can’t seem to find anyone I really want to follow except Rick Rubin and Steve Jobs so hopefully more artists start supporting the network. Ping really seems geared to selling downloads and creating a human version of Genius to recommend music to your friends and followers. I would love to see ping support other aspects of iTunes such as Apps, Podcasts, and iTunes U maybe Apple is saving that for later versions
update – Just an idea you should be able to follow or like from your library.
