I have seen the future, in my addled little mind, and it is an MP3 Vending Machine. This link is to a pic of a vending machine selling iPods, which is really rather gauche (yo, rich guy—where y’gonna get some tunes before your flight boards?).
BUT…
An MP3 vending machine, where you could plug in, swipe your credit card, and grab some tunes from say, The Life Aquatic soundtrack before hopping on your plane…
Now, that, my friends, would be superbad.
