Geez some of the reactions here....

"NoT *****y M$ WinD0z oN My l337 H4x0r B0x!!!?!!!"

I still use my n900 as my daily phone, its the only phone I own, and yes it has its merit (although admittedly I am counting down the months until I can upgrade my contract...)

I wont be getting a win7 phone because I do like multitasking and it is too limiting, but its about doing it so it can be done. I dont think anyone said "I really NEED a copy of windows 95 on my n900 that takes 20 min to load", it was done simply because it could be..

You would think the guy asked if it was OK to fool around with his sister from some of the reactions.. not simply asking if one of the 3 biggest OS's in terms of mindshare could be run on his supposedly very open and modifiable phone in a community that supposedly prides itself on modifying devices and pushing the envelope on what the device can do simply because they can.... guest he must have come to the wrong place...
