N900 == not meego. and from scratch not QT. now the engineers inside nokia is both using the QT framewoirk this means crossplatform apps for symbian and Meego. Difference before was that N900 was using Gtk and Symbian its own App framework. So I am sure this is changing alot now when both will use mostly the same core UI == make it simpler to port between all platforms (inkl. maemo) == more developers makeing crossapps instead of reinvent the wheel..
