Those ZoomSystems iPod vending machines that we once gently mocked are both more successful and more ubiquitous than we thought they'd be. Still, it seems they aren't flawless.

[That's a joke, in case our visitors from Digg are confused. While there are plenty of Point Of Sale systems for the Mac, I don't actually know of one that's intended for vending-machine deployment, and even a Mac Mini is a bit high-end for the build cost of vending machines. That aside, it's probably not the best call to go with XP for a vend setup either...]
