Nokia is great, and have zero market share in the US - even when they ruled. What is your point exactly. The US is ruled by operators, not by the free market. Mango is just excellent and this time it is coming on real quality hardware - from all the big ones. It is doomed to succeed. I am really quite puzzled by the nay sayers here. Are you blind?

Android had 1-2% market share the first 2 years at least. iOS still only have 4-5 % market share globally.

Regarding Android: Samsung sell Android, Android does not sell Samsung. From now on Samsung, HTC, Nokia and LG will sell WP (Mango), and it will start with a bang that only gets loader and loader.
