The main advantage of AppleTalk was that it was completely maintenance-free. To join a device to a network, you simply plugged the adaptor into the machine, then connected a cable from it to any free port on any other adaptor. AppleTalk's internal protocols negotiated a working network address number, automatically gave the computer a human-readable name, and collected up a list of the names and types of other machines on the network so the user could browse the devices through the GUI-based Chooser. AppleTalk was so easy to use that ad hoc networks tended to appear whenever multiple Macs were in the same room. Apple would later use this in an advertisement showing a network being created between two seats in an airplane.
