Microsoft is launching a $300 million ad campaign starting September 4th, says the WSJ . The ad campaign will star comedian Jerry Seinfeld and Bill Gates, and it was developed to combat the negative image that many consumers have about Windows Vista and also to finally push back against Apple’s popular Mac vs. PC campaign. Really interesting move by CPB, which after winning Microsoft back earlier this year finally shows the big idea.

A new video featuring Jerry and Bill showed up yesterday in YouTube, and my first reaction was WTF! I’m sure CPB has something really good planned, they always do, and perhaps this is intentional, but seriously, what is this?

It reminds me of a famous Steve Jobs quote on Microsoft: “The only problem with Microsoft is they just have no taste.”
