Nobody talking about this yet? It doesn't work for the older-than-3Gs phones... and similar older generation iPod touch... but for everyone else, there's at least one really cool feature. You can now stream from your iTunes library via Wifi to your iPhone or iPad. So... you only have to load up your device with songs/videos that you need when outside the home... You can leave a lot of your library on your computer and stream from there while on your home network. I tried earlier with my iPad and it works pretty well... I like not having to load my iPad up with movie files just to watch them and delete them afterwards... now I can just leave my iTunes running and watch on the iPad whenever the whim strikes.
