While i don't think it's wrong to say that Nokia failed in TS market they in 2009 already became largest TS phone manufacturer. The thing that they are missing is truly new UI for 2010.

Symbian is funny in a way that it's very advanced. It got demand paging for 4 years already and S^3 will be the first one from the major OSs to use GPU to help when browsing UI for example. The seed of all problems behind Symbian is AVKON and the weird Symbian C++ framework that comes with it. This means that while there is over 200 million Symbian phone out there OVI store got ~10 000 applications compared to iphones 150 000. With AVKON you can also go just that far with the UI design.

If there's a Nokia saver it's not MeeGo, it's Qt. Symbian will actually be the new S40, new volume OS and Harmattan MeeGo will be the Symbian that it was for it's first 5-6 years. Qt based Symbian(S^4 and everything after that)will be at least just as important for Nokia as Harmattan/MeeGo(that will be the first Qt based) that will be true high end OS and i'm very happy Nokia did that.



Qt and QT SDK takes application development to a different level and you can wait some actually modern feeling UI's and looking. Anybody who have tested Widget Gallery probally understands why i'm talking about modern feeling UI's.
Qt is no win button, but it sure gives possibility for Nokia to make Harmattan something actually better than iphone in pure UI sense rather than just something that's ok. Hopefully Nokia can deliver with Harmattan/MeeGo because i really like the idea behind Maemo.
