I'm fairly new to my N900, but the main reason I got mine, I'm sure like many others, was the amount of freedom with the phone.

I'm very impressed by what people have managed to do OS wise just because the wanted to try, running win 3.1 etc and recently, porting android to the phone, and i think I remember reading of open pandora too? I may be wrong.

But one thing surprises me, that I've never seen anything of windows mobile being hacked onto the phone, especially considering the similar hardware platform.
Is there any reason for this not being ported? Or purely a case of no-ones tried? If there are hardware reasons, please tell me, I'm quite intrigued, I'd have a try myself if I had any idea where to start and wasn't likely to brick my phone
