Microsoft has pushed Seinfeld to the side for their new ad which actually features people talking about computers (not leather shoes). The PC plays the victim card and has "been made into a stereotype." They can't really claim to be victims since they still dominate the market, despite Apple gaining some market share on them.
They probably should have gone with another message. Although, this commercial is lacking something that the first two weren't: buzz. Look at all of the word-of-mouth that was spread online by bloggers and journalists. Each of those commercials have been watched over 1 million times on YouTube. This one is as forgettable as every other ad you see on TV.
