I think the very latest MeeGo news has changed everything. As I've said before, the n900 is a one-off. A pure transitional device.
Everyone raise their hands who think Nokia will ever use a resistive screen again in one of their high end devices.
Now, combine (a handset) with the latest Qt eye candy. Cool, let's add in an OS. Take your pick: Symbian, MeeGo, Harmattan, LG's MeeGo, ..., etc. If Qt 4.7 can truly hide 98% of the OS from the application developer, f*ck Android. Again, with the latest MeeGo news, porting Android might have just gotten a hundred times easier. And without even knowing it, I could be a Symbian developer by this time next year.
There's no good reason why Nokia should throw in the OS towel at this point. Or ever, really.
