Skeuomorphic design. It's a funny old thing. "It’s visual masturbation," says one former senior UI designer at Apple who worked closely with Steve Jobs. "It’s like the designers are flexing their muscles to show you how good of a visual rendering they can do of a physical object. Who cares?"
Now that's a good quote.
The best example is the shutter sound on your mobile. It's a weird habit we have of clinging on to old design when it serves no purpose whatsoever. Apple are big fans of it (although there are rumours of a rift) and it'll be very interesting to see what they've done with the iPhone that's coming out later today.
Anyway, here's a site dedicated to skeuomorphism, called, suitably, Skeu It!
