Each time Steve Jobs takes to the stage to introduce the drooling press and public to the latest Apple gizmo, he shows a "PC and Mac" advert.
Now Apple UK have produced a local version - which can be checked out at apple.com/uk - using Mitchell and Webb from the Channel 4 comedy show I can't remember the name of! (Update: "Peep Show" I'm reminded.)
But from the look of the ad in this morning's Guardian, Mitchell makes the perfect uncool and boring PC, while Webb has the flair and X factor (OS X factor!) to be a Mac.
Except they're both twits.
