I have to agree about the Mac vs PC ads, they were bad enough in the UK (Dave, Rob, what were you thinking?) but I was on holiday in the US and saw one of the ads on the TV, it seemed like they were just saying that Bill Gates, and therefore by extension all Windows users were socially retarded idiots and that Steve Jobs and therefore by extension any Mac user was the coolest thing since James Bond. I was quite shocked.

I generally speaking detest any of the new form of advertising whereby direct specific comparisons are place on the major competitor, you know the stuff: At Tesco X costs Y, but at Asda it costs Z, it just makes me think that everything else is not comparible. If a product can't sell itself and needs its competition to be sold, it's probably not that good.
