Microsoft is planning an online ad campaign that would pit Windows Phone 7 against rivals in a speed showdown, a leak of draft spec commercials (below) has uncovered. Each of the Flash-based segments, known as "Real Time Trials," will show how much quicker a WP7 device can accomplish a given task versus a rival phone, such as posting a photo to Facebook or letting those in a meeting know you'll be late. The "your phone" outlines are placeholders, WinRumors said, and would likely be filled in by a video of a competing smartphone doing the same thing more slowly.
