I have also written Qt apps for the N900, and having used several IDE's and several platforms I have to say that Qt is excellent. And QML is icing on the cake. It really makes creating mobile apps simple. I don't even have scratchbox installed...I just go straight from QtCreator to packaging for the extras repository.

Supposedly Angry Birds and Bounce were written with Qt. Angry Birds is one of the most popular games for Android and for iPhone, so it is nice to see Rovio (the publisher) picking up on Qt. It bodes well for the future.

I don't know if this is the tenor of the thread, but I do see a lack of cross-platform Qt content for the N900 (or in general). Are there tons of Qt apps out there for Symbian (or even desktops) just waiting for us to find the open source code and port them? If so, identify the locations and we will start porting. But the expectation is that the development for symbian should also be creating apps for N900 and meego.

Perhaps now that meego devices are beginning to hit the market (a few tablets, at least), we will start to see some action. But don't let that stop you from writing in Qt...it really is the way to go if you want to make apps for these platforms going forward.
