We must realize that this will not stop at iPods. Necessary adaptors will emerge, and people will be bringing their Wiis and XBox 360s onboard Boeing craft in no time. But wait, it doesn't have to stop there. In order to impose any form of content control, the entire system of iPod-to-screens will need to be centrally wired. That means dozens of iPods, all on a central network. All you really have to do from then on is bring your laptop, an enormous external hard drive, and the right cables, and you're in business. The selection of movies and music will be nothing short of impressive. And if you get bored with that... well... who says you can't hack a 747?
