To me the only thing killer about the iTunes integration for the iPhone is that it almost kills the experience for me. I would really like to get rid of iTunes, but I can't since I need to use it to sync my iPhone. For music I use Spotify, and Spotify has applications for both iPhone and Android. I also listen to podcasts, but I would like to manage that entirely from my phone instead of having to use iTunes to download the episodes. I know you can get new episodes with the phone, but that is far too manual and requires WiFi which I keep turned off to save on battery.
