Where exactly do you think those high end smartphone markets are? Where do you think Nokia ruled with the N95 and had more than 50% of global smartphone market share? It was not the US. By todays standard, what is a "smartphone market" anyway, what is a smartphone?.

The N9 is going to markets where people change phones often (one new unit in less that 18 months), markets where people have more than one phone operational on average (typically 1.3-1.5 phone per person), markets where people in general are early adopters. It is going to free markets where operators have little to say in the matter and where people don't think twice about purchasing unlocked phones (they may still buy phones from operators, even including a plan of some kind, but that's a different subject altogether)

The N9 is going to specific European countries and to Asia including China and some other places. WP is going to more operator-controlled places like Germany and UK - and in particular the US. WP will eventually take over, but in the mean time the N9 will rock the market for a year or two and will become a classic while doing so. Harmattan may or may not disappear, but swipe is here to stay for sure, you will be surprised.
