Dunno if you guys heard, but basically Nokia is in serious crisis these days (because they failed to turn their market domination of a few years ago into a competitive advantage), have abandoned definitely their linux-based MeeGo OS and have arrived at a point where their only options were to choose an outside vendor. Android or Windows. They chose Windows.
Evidently, Nokia's "more open than Android" was just the briefest of flashes and they have now returned to what they do best: complete proprietary stack. Awful.
