Apple said they have no plans to support any player but the ipod. I don't know if that means they won't license it or that they won't actually do the programming.

Did you look at any other service musicmatch, napster or buymusic ? I would guess those all work since the are linked on the rio website and they use wma.

I agree about the headphones they must have only tested uning dwarfs or people without pockets.

I agree about RMM it works very good for managing the music on my computer as well as the karma.
