First in the Atlanta airport (and now in other airports, malls, and hotels), Apple iPods are being sold by special "robotic product delivery systems" that offer the music players along with other stuff such as digital cameras and snacks - just in case you want to eat peanuts while snapping digital photos or listening to MP3s. In the past, we would call these "delivery systems" something like "vending machines," but Zoom Systems, the maker of these devices, insists that its units are much more sophisticated than that. Has anyone out there actually seen one of these?
