Windows Phone 7

Windows Phone 7, which will make its debut in some European markets on Oct. 21 and in time for the holidays in the U.S. The phone uses an elegant operating system that is very different from the current trend toward app-focused phones. Instead it provides active and configurable interface elements called tiles that update on the fly with real information, allowing users to place the tiles that interest them most where they want on their Start screen. Facebook photos, music and contacts are pulled into the phone and distributed appropriately across Hubs. It also brings together many of Microsoft’s popular offerings from other platforms, including Xbox, Zune, Office and Bing.
