Windows Phone Mango demoed by Microsoft in dramatic fashion (video)

Sure we've seen plenty of Windows Phone Mango demos -- heck, we've done a few hands-ons ourselves -- but so far as slickness is concerned, few can compare to this latest offering from Microsoft, which looks to bring developers on board, while showing off some key features like Live Tiles and speedy switching between apps in dramatic hands-off fashion. The Mango is so close we can taste it. Video after the break.
