I'm becoming an Apple fan more and more ever day. A few days ago they just released the new iTunes, version number 7.1.
Using iTunes 7.1, you can now enjoy your favorite iTunes movies, TV shows, music, and more from the comfort of your living room with Apple TV. iTunes 7.1 also supports a new full screen Cover Flow and improved sorting options to let you decide how iTunes should sort your favorite artists, albums, and songs.
If you are interested in the full release notes, you will be disappointed, as they don't say much more than what I just quoted above.
You can get the new iTunes 7.1 from the Apple site, or wait till your Apple Software Update detects the new version.
