We're live from Microsoft Windows president Steven Sinofsky's keynote at D9, and there's something rather exciting on stage -- a pair of experimental Windows 8 dev boards running an OS that looks very much like Windows Phone 7's Metro UI. All Things D actually sat down with the man earlier today and got a sneak peek at what to expect starting with the live tiled screen you see above -- and yes, like Windows Phone 7, this OS is designed for touch.
All Things D didn't have any details on when we'll get pricing or availability, but we're looking at some Intel Atom-based demo units on stage right now, and Microsoft says it will have ARM designs (the OS will support NVIDIA, TI and Qualcomm) viewable on the Computex show floor, and more will be revealed at the Build Windows developer conference in September. We should note that "Windows 8" is just a codename for what we're seeing here -- "we'll figure out the real name in due time," Sinofsky told the crowd -- but we don't see much harm in calling it Windows 8 for now.
