Not sure exactly why you'd need this, but in case you were dying to know when and where your Mac or iPod were built, the CoconutIdentityCard is an application that gives you that information instantly. It currently only works with Mac OS X 10.4 and up, though it should also run on upcoming Intel-based Macs as well. For the iPod info, just plug it in to your computer while the app is running, and voila. Oh, it doesn't work with the iPod Shuffle, by the way. Guess nobody really cares where or when they're born.
