Maybe more important for some in the long run is that there is no demand for WP7 whatsoever. Maybe it will pick up, but so far nada. The iPhone and Android in particular is a long way yet from saturating the market. Android and iPhone is still the new thing people want and WP7 is irrelevant (expensive, full of limitations and well, Microsoft). And there is Symbian with N8 that every blogger in the US love to pick on. Nokia with all its mighty production power, cannot produce enough units. It is the most selling phone at the moment, C6 C7 and E7 is out to larger or lesser degree around the world, but Nokia cannot produce enough.

My theory is that WP7 just isn't sexy. Android is so so but iPhone and N8 got this little extra.

Nothing compares to the N900 either way. It is not the most selling device. It is rough on the edges and hated by many. But there is nothing like it. It is like an old Jaguar E type.
