WP7 has no future for me anyways. When it launched it was/is still lacking all kinds of stuff e.g. compared to Maemo5 PR1 in terms of functionality. Then depending on upgrades from M$, thats a no-win. Not able to flash as compared to ours, no-win. I could make this a long list but you get the idea..

IMHO it was garbage from the start, and knowing M$ it will stay garbage for quite a while. Maybe it is best compared to iOS, plus the handicaps it drags along the road.
