Apple's alternate Macworld 2008 teaser ad leakedA tipster sent us this alternate version of the Apple teaser ad currently up on Apple.com. According to our tipster, Steve Jobs spent hours meditating to choose between "air" and "water" themes for Macworld. What could "There's something in the water" mean? We can only speculate, but our best guess is a waterproof ultrathin notebook called the MacBook Water. The MacBook Water was to be specifically designed for scuba divers and other water-sports enthusiasts. (Ahem.) Have any more information? Leave a comment.
