Wp7 would be the last thing i would move to. Anyone here has a windows phone? I have a Htc HD7, and i am totally NOT impressed by the Os. Sure it is nice to have an alternative, but i wouldnt want it.
Maemo is just too superior to me. IOS, Android, whatever you say, i have used all of them and they get boring after a while, and playing games on it is just to childish...at least for maemo users, trust me ps3 is much better.

For 2011, i wish i could have a modern Maemo tablet.
