Yesterday, at the All Things Digital conference - usually something I avoid - Microsoft unveiled the new Metro style user interface for Windows. Optimised for touch, but compatible with a mouse and keyboard. Alarmingly applications that make sure of this user interface are written in HTML5 and Javascript. Hopefully Silverlight, and even WPF will make an appearance in the future.
It also looks like the Office team have finished their takeover of Windows, with Jensen Harris in charge of the video!
All in all I'm impressed with the direction they're going, I'd argue they could have done it sooner. They've had the key aspects in there for years, namely with Media Center from which Metro was derived. But now with Windows also being ported to low powered ARM devices it was clear a full-featured Metro style interface was needed.
