I think the point is that your success with Qt doesn't really have a lot of impact on the possibility of Nokia shipping a successful consumer-mobile phone that happens to have a UI written in Qt.
No, my point is that Qt is not a project that is only used or cared about by "a few geeks". Many of us use it to build and ship real products, and we could give a rat's ass what Nokia does in the future. But don't dismiss the project as a toy or trivial idea (I can point you to Java Swing if you need that).
When I said that "only a few geeks would care", I meant it as a selling point for consumers or developers. "Hey, this phone uses QT, buy it, develop for it!"
I did not mean applications like yours and never implied it was a toy.
