In a nutshell, the campaign is "Watch us humiliate you and the phone you are spending a lot of your hard-earned money on." Why would anyone think that making consumers feel bad is going to lead them to having the warm, fuzzy feelings necessary to buy their product?
Last year's marketing for Windows Phone was awful because it didn't show the phone. Show the phone! It looks great. Tell consumers why they should want it. Not "it does what your phone does, just a bit faster in rigged competitions." Show it working with Xbox. With Hotmail. Show its hubs. "Ever wonder what Dave is doing? On Facebook? On Foursquare? On Twitter? Now you know."
Apple and Google keep knocking their campaigns out the park because they're built on honesty. Microsoft's campaigns are built on gimmicks and bullshit, and it shows.
