The above video shows a task speed test between the iPhone and a Windows Phone 7 device (Samsung Focus), which included the following steps:

  1. Take a Picture
  2. Upload Picture to Facebook with Caption ("Check out my new hat!")
  3. Update Status ("I love weekends!")
  4. Find Directions to a Restaurant (Olive Garden)
  5. Get Movie Times ("Fast Five")
Unfortunately for our iOS friends, WP7 comes out tops due to it's simplicity and superb social integration. Does this remind everyone of the previous comparison adverts Microsoft released

Thanks James for the tip!
