If you buy into that kind of 'analysis' NOKIA are still a very big brand in Asia:



Personally I see sales figures as rather more concrete evidence and sales of Symbian devices were huge and still growing prior to Elop's brain fart.

I understand if you extrapolate what NOKIA were doing before Elop's execution of Symbian and compare that to what they are doing now you have a deficit of around 70 million devices so far.

Even if Symbian was the problem WP7 clearly isn't the solution.
