Nokia has already lost many times over. 25% and counting already lost from Nokia's asset balance since the news of the MS-elop pact leaked out. Nokia could've bought Linux #2 Novell (large patent & IP portfolio, Qt/GTK/.NET/Mono developers, also working on Meego) for a fraction of this lost valuation.
Ballmer did not lay awake at night worrying about a framework primarily used for Linux desktop KDE applications. Can you think of one major piece of software available on Windows, Mac and Linux that was written with Qt?
as i have seen with intel's prototypes in MWC (video), meego still has a long way to go in terms of development as compared to an already polished, and currently already selling WP7 OS.
