Windows Phone 7 Demo Video
Here is a demo video of the UI direct from Microsoft. I will have my own videos soon enough, but right now, my hands are tied. I’ve had some hands on in a 1 day classroom-type environment, but not in a real world environment. I expect to have a device in hand fairly soon though.
This video includes a demo of the Windows Phone 7 user interface and footage of nine Windows Phone 7 devices available worldwide.
