Microsoft kicked off a $300 million marketing campaign on Thursday, aimed at improving the image of its Windows Vista operating system and strike back at Apple Inc's "Mac vs. PC" ads. The first commercial of Microsoft's new marketing push, being created by advertising agency Crispin Porter + Bogusky, aired on Thursday featuring comedian Jerry Seinfeld and company co-founder Bill Gates at a shoe store. Despite selling more than 180 million licenses since its launch in 2007, Windows Vista continues to suffer from the perception that the operating system is clunky and hard to use compared with Apple computers. That image has been stoked by Apple's "Mac vs. PC" ads featuring a geeky and unfashionable PC guy unable to keep up with a better-looking, hip Mac counterpart. Well, maybe it would be better to use that $300mil to give everyone a free copy of Vista as proof-of-concept or make it cheaper :-) So what do you think? FYI, I still have Windows XP...EVERYWHERE :-)
