It’s been announced as the ad war of the year, if not of the decade. The Microsoft empire, tired of being cast as a stodgy oldster by Apple’s rebel advertising, would strike back with one of the largest advertising campaign in the company’s history and spend $300 million in a killer-ad featuring the popular Jerry Seinfeld. Wow! Gates vs. Job. The great old tycoon war revival. Can’t wait.Well, here is Microsoft’s new weapon of massive destruction, launched September 4.Okay! Is there something I don’t get? A new marketing 2.0 era with subtle hidden irony maybe? The “season premiere” of an exiting series of upcoming episodes?$300 millions for that. I would be fired.But more importantly, I certainly won’t give up on my Mac for a pair of cheap shoes Want some pizza with it?
