Every time Apple introduces a new product they love to compare it to a common object that shows just how magically small it is. The MacBook Air fits inside an envelope. The iPod Classic is the size of a deck of cards. The iPad mini is thinner than a pencil. And the 4th generation iPad with Retina display is thinner than a penny! Wait, what?
A typo on Apple’s website says that the depth of the iPad is .37mm, which would make it about as thick as four sheets of paper copy. For sake of comparison a penny has a depth of 1.57mm, so the new iPad is hella skinny. Obviously the image should show .37 inches thick, not millimeters. We’re just surprised this little mistake has slipped through Apple’s perfectionist fingers without much notice.
