Our first taste of Windows Phone 7's Mango OS was delectable, as the revamped UI brought together stunning animations and enhanced productivity features like real-time updates. Microsoft gave its Bing search engine a facelift by including Voice Search, a Shazam-inspired music app, and search aggregation tool called Bing Vision that pulls info from an item at which the rear camera is pointed. The intuitive software provides a major boost in speed for the dated 1GHz Qualcomm CPU that places the WP7 device on the same performance level as many of the lower-tier dual-core chips out. And what better way to top off Microsoft's mobile delicacy than with a sexy veneer frosted in all-white and silver accents. Bon appétit!
