iTunes supporting Android would be great for Apple. Unfortunately, it would also be good for Google, so it's never going to happen.
Eh? Winamp, DoubleTwist, Spotify, and even Windows Media Player all sync flawlessly, and Google Play Music and Android Cloud Player work great, too.
I'd guess a lot, but even if that's wrong, it takes hundreds of incremental music sales to offset the loss of just one iPhone sale.
Amazon MP3 works flawlessly. Who needs iTunes?
