In an attempt to escape the "boring" box that Apple has firmly placed it in, Microsoft is spending $300 million on a full scale marketing blitz. After a disappointing reaction to the first stage - the Seinfeld ads that nobody understood - stage two, "I'm a PC", was launched on Thursday.

Apple has gone from strength to strength in the past decade and in 2006 felt itself strong enough to start bashing its biggest - and once much stronger - competitor. After years of losing face to the ‘Get a Mac' campaign, Microsoft has launched a direct attack in response.

The first part of the campaign, a somewhat confusing and not all that funny pair of videos featuring 90s sitcom star Seinfeld, was largely ignored. After just two weeks of airtime, the ads have been replaced (some say they were pulled early). On Thursday, a series of TV and viral clips featuring a collection of supposed PC users from around the world emerged. Opening with Microsoft employee Sean Siler, who says "I'm a PC and I've been made into a stereotype", the various PC users then demonstrate just how eclectic and exciting they are. Microsoft is spending around $300 million (€210m) on the marketing blitz, which will introduce their new slogan "Life Without Walls".
