What's up with the gtk obsession? Maemo 5 UI could have easily been written on Qt, and it'd probably have resulted in less lines of code and better quality than the gtk version. Maemo 5 was written in gtk because the whole push into Qt and QML came later than N900's development. Even if MeeGo didn't happen and Nokia would have continued with Maemo base, the push to Qt / QML would have happened anyway. And in my opinion quite rightly. Qt is much better and easier framework than gtk.
