The iPad officially comes out tomorrow and people are already waiting in line to get Apple's most talked about new gadget. Last night, David Letterman devoted his "Top Ten" list to the iPad, and even tried the device out himself, which was sort of like watching a monkey trying to work a radio. He did point out one good thing about the device, however: it comes preloaded with photos of a family. "So you're not just buying an unnecessary electronic device, you're buying a family!" Dave said, right before he licked the iPad to try to turn it off.
