Your information is woefully out of date. Symbian is not going to be in high-end Nokia devices. The most powerful Nokia devices will be MeeGo based. Qt is there to make development easier for Symbian and MeeGo (at the same time). Go ahead and research something about S^3, S^4 and Qt. Things are going to improve for developers. In fact, by developing in Qt, you are developing for both Symbian and MeeGo at the same time. Nokia grew marketshare last quarter, alongside with RIM and Android (Apple's remained flat).
