I don't think this piece has taken into account the fact that Nokia isn't jumping onto the "ice cold" Windows Phone right now, but a software iteration downstream.<p>It looks to me as though Elop has taken the decision that the best chance Nokia has to leverage the assets it has created in its own historic portfolio is through a credible platform it can (at least partly) steer.<p>The multi-platform guys haven't gone all out for WP7 - why would they? And operators have been tentative. Nokia's arrival in this space is huge for the platform, and huge for mobile network operators all over the planet.<p>But what's also huge is the risk. Apple's doing OK, but Android is snowballing. 2012 is very, very late to get in to the smartphone 2.0 party.
