There won't be much to do on/with Windows for the Pi 2, the only thing people will be porting to it is the same open source software that's on Linux for the Pi, buy why take all the work to do that and accomplish basically the same thing that's already possible with Linux? Practice for developers I guess, but I don't see what new opportunities having Windows on the Pi will do, it's not like that will bring along the Windows software ecosysytem. It will be the same ecosystem we already have on Linux, except piece by piece and not everything will be there for a while. It will be easier and faster to get up and running with Linux on the Pi. Will Windows even be able to catch up in this niche that's already so well served?
