I just say the same as others. It's all about the carriers.

I remember reading from quarter report that Nokia sold over 400k N95(all variants) in NA. So i guess N900 could have it's space to move in NA market, but no doubt N900 isn't yet enough. Symbian is special that it controlled European and Asian market, but was left out in NA when it still was in many ways better than it's competition, but now can't see Symbian coming back to NA other than form of Symbian^4.

So Maemo it is. As/if maemo comes the Nokias high end OS and it gets as much as attention as Symbian from Nokia and start churning different phones out in a same rate while these phones are advertised, hyped and subsidies, why not?
