This is ridiculous. What are you going to run on your windows Pi? Play games?
Good luck with that. This isn't Windows as you know it - there is no desktop, not even a cmd prompt. Remote PowerShell is about all you get at the moment as I understand it.
So what will we be able to do with it? I was going to get a new laptop soon so it would have had windows so I would be entitled top the pi version but if the pi version is rubbish I might not bother.
