I'm far from a Symbian fan(Yes I'm a Maemo fan ), but a lot of people are mistaken about Symbian. The platform is far from dead, I agree that it has some problems, one of them is Symbian C++ (horrible), but Symbian is a very robust, complete and stable OS, at the moment, the major problem is the outdated UI.
With Qt's help I bet it will have a new life, we'll see who's wrong .

Anyway Maemo will rock.
