Does Nokia gain a superior OS out of Microsoft? No. Phone 7 won't even be able to run all the features that current Nokia premium phones have. So right from the start, this means moving Nokia abilities down a notch.

But competitive advantage? Differentiation. Well, who else is committed to Phone 7? Lets see - Samsung, LG and SonyEricsson. So whatever Microsoft is developing, Nokia cannot even have any significant advantage - on its premium phones - that Samsung, LG and SonyEricsson don't know about. They gain all the delays of Microsoft while gaining also the eyes and ears of most of their biggest competitors to see all the development. When before, on both Symbian and MeeGo Nokia would have had their development to themselves. Yeah, *****ic move.
