I never got to understand all that maemo, symbian, meego operating system differences. Couldn't they just use linux and get some QML frontend in front of it. It seems really a lack of direction/duplication of efforts.
What do you mean exactly?
The only thing I am afraid of losing if Nokia goes down is Qt.
If I'm correct, the Qt Lighthouse is integrated in Qt 4.8 (now RC1), which means easy porting for any platform, including Android. Remains to be seen if Nokia and Google come in terms with this officially though. Of course, you can already distribute Qt apps on Android, using third party ports like Necessitas: http://labs.qt.nokia.com/2011/02/28/necessitas/ .
