With all these new devices, who knew Apple had time to do work on iTunes as well? iTunes 10 is now available for download, and even sports a new logo as a feature. The biggest change is the introduction of Ping, a "social network for music" that has been added to iTunes. Like Twitter, Ping allows users to follow each other. You can see what people or artists are listening to or creating, get news feeds, concert listings, and song and album charts. Ping will be available to 160 million iTunes users, and will be available on the iPod Touch and iPhone as well as the desktop.
