What, by coming out with a player and a music download service that uses a proprietary DRM-protected file format?

AAC is propritary? Anyhow, the end user dosen't care that their player uses MP3, AAC, WMA or whatever. They care it plays their music easially.

Apple has a good chunk of the digital music market now not because of one thing. But because of several. Marketing is a big one, and the solid integration. Being able to install iTunes, start putting in CDs, and then plugging in an iPod to have it sync automaticially is amazing to end users. Rio by what I understand is getting closer with the newer Rio Music Manager to this type of integration, and I am glad to see it.

Random question, how close to the iTunes install/rip/sync is the Karma? Mind you, I never enter a preference screen, ever bother with manual driver installs, and hit about 6 next buttons.
