Thats my point, if you want the apple store to be as successful as it could be, it has to have OTHER players that can play the media it sells - right now, ONLY the iPod is compatible with the store - thus proprietary hardware is required to use the store and play its music, despite it being an open standard. Others need to adopt it for it to be a relevant standard. People will buy songs they can play on their player, and yes while there are a lot of iPods, its not the whole market, and as better and better wanna-bes come into the market, I see the windows crowd (the vast majority of users) eventually resorting to the same purchasing petterns as their hardware - cheapest, fastest, biggest. Without regard to build quality, HI, intuitive-ness. People won;t spend the big bucks on their second iPod, when nomad, etc makes a cheaper, bigger one. iPod's not the only game in town...
Hope more players start embracing AAC, this would help the iTMS tremendously
