They're in the same position that Sony was in: late to the party. They can't afford to charge for it. They weren't the trend sitter. BTW, the same can be said for Windows Phone 7 too. They're not charging for it either because they're late to the game on the phone too.

I doubt that's true. Apple's late for a few things and they still charge for what's fair to them. Phone gaming is meant for a different crowd. They may be unlikely to pay to begin with.
