Well, obviously this means you can watch WMA and WMV on Zune software for Mac. I think this is good, because Mac people hated WMV because they can't play it, but they don't have the same problem anymore. They can still be a fanboy and like that annoying jerk trash talking on the TV ads. But, at least they will have more experience with Zune or WM formats. It is good for future format adoptions.
