Microsoft has posted a video that’s chock full of inspirational music and provides a nice overview of the features found in Windows Phone 7. More than anything else, it’s a nice tour through the beautiful UI (user interface) of Windows Phone 7. The teaser video reminds us that it’s coming Holidays 2010. Hang in there folks, it’ll be just a few more months. In the meantime, you can discuss the new OS in our Windows Phone 7 Forum.
