I understood all the technical reasons why to focus on the Harmattan version, thanks for the explanation. As already said probably you mean by that Ovi Maps on Harmattan will be based on Qt4.6 while current Ovi Maps on Freemantle is GTK, right?

What I can't understand is why Nokia spent resources developing this GTK version, which is being constantly criticized due to lack of turn-by-turn navigation, when they could launch N900 without Ovi Maps at all. Maybe then we could get a fully functional Ovi Maps together with Qt4.6 framework due to the next firmware update.

I guess the reason to invest on a GTK version could be either technical, to detect bugs in features like routing calculation that shouldn't need porting to the Harmattan version, and/or even commercial demands, just to avoid launching a device without GPS application, which could hurt sales since competitors have it.

At least one thing I think most member will agree: the current uncertainty on Maemo/N900/Ovi roadmaps is just diverting attention from the collaboration itself.
