On the other side,

If Nokia wants to promote that Qt is "the solution to all your multiplatformness - Symbian, Maemo 5, MeeGo, ... - needs", and not even their own applications are truly multiplatform...

yet another reason for me to believe that this promised commercial multiplatformness is never going to materialize.

I say Ovi Maps is a prime candidate of a well isolated application where the same codebase could easily be shared between platforms -- make them eat their own Qt dogfeed!
