So did Bill Gates toss down a gauntlet in the MP3 player wars or not? In an interview prior to the big launch of Vista and Office 2007 with Kevin Maney of USA Today, Gates said,
"If Apple said any song on the iPod could be played on Zune, we’d say the same thing. Because they have such a high market share, they’re not interested in interoperability, but that’s too bad."
Don't count on the gauntlet being picked up any time soon.
