The iPad finally went on sale at 9 a.m. this morning. Three hours later, the Internet is churning out content by the second about this world-changing, cancer-curing, vegetable-chopping device. Gizmodo is live-reviewing as many apps as possible. Engadget is already finding problems. IFixit is tearing the damn thing apart. And the Times is documenting the pandemonium at the city’s Apple outlets. But if there is one essential piece of media you should consume in these first few hours after the release of the device that will make you more attractive and funnier, it’s this video of Steve Wozniak performing a magic trick while waiting in line for his three iPads.
