Is your phone faster than a Windows Phone?

Microsoft issued a challenge at CES to see if your phone could smoke a Windows Phone

We've heard claims by Microsoft that Windows Phone is far more efficient at everyday tasks than other phones on the market. Well, the Windows Phone team issued a $100 challenge to anyone whose phone could beat the Windows Phone. To make it fair, the team even let the contestant choose the function that they would be performing on both phones.

In summary, the results will surprise you. In almost every instance Windows Phone smoked the competition, as you can see in the video below.

This video got me thinking that I should start messing with my Windows Phone again. It's a sweet interface, but I never thought it would actually perform everyday tasks faster than my iPhone 4S.

What phone do you use and why?
