I wonder why interoperabilit y should be a big issue for them and for DRM. They would have to offer as any other legal music provider a DRM convertor so people with AAC could get WMA and vice versa. Apple is not the only provider concerned, Microsoft and others are too. I guess Apple's french speaker is a bit confused since she acknowloedges that could hurt their Music Store Business and profit their iPod business as well. Since people prefer iPod than any other mp3 players and recognize that Music Store is far more efficient than any other services (i.e Sony's Download Service that failed or even MSN), the interoperabilit y could be more profitable than what they say.
