Mac.co.uk

They use two different dudes in the ads here.

I think both of them are actors in a pretty successful show here called Peep Show. Until a few days ago, I thought "PC" was a magician.

Apparently the ads aren't very successful here (actually they're the opposite) because everyone thinks "Mac" is kind of a dick, and many non-Mac users think of Mac users as being a little pretentious and self-righteous. Which, in some cases, we are.
