I wonder if mobile market share had anything to do with this...
When they integrate iTunes support to XBox then you'll know for sure LOL
Well, they hit their own mobile first, then expanded to the popular iOS platform. Seemed weird at first, the idea that Apple would allow a Microsoft-developed app, but then it's aimed at the gaming console crowd and Apple doesn't have a stake in that.
