It hasn't been released yet from what I heard. I think it will be crap compared to the open-source Android platform.
The Windows 7 phone HTC is working on looks nice but a little IPhone like. As Jay said, it doesn't look like it has come out just yet. Honestly, as more companies start to push out Android I see it dominating the market and overtaking BlackBerry's soon. Being a BlackBerry FanBoy, I think I might switch over to an Android phone myself once my contract is over with Verizon.
iOS4 and Android OS have outsmarted Windows based phones by a great margin. Like a lot of Microsoft ventures,it in my opinion it will turn out to be a failure project.
