Start screen

Microsoft is showing off on Monday the new version of its long-anticipated (and oft-delayed) mobile phone operating system. Here's a look at Windows Phone 7 Series' very Zune-like interface.

The central point of the new start screen are various "live tiles" which can be used to point to an application, a hub (such as photos or music), a Web site, or even an individual contact. Like a widget, such tiles can also contain various status updates, such as the number of new messages.
