when all the surfaces are plastic or rubber? It couldn't be for
parts beyond the black box becasue the wire from the box to the laptop
is just two wires.

Is it just to make people who are afraid of computers and elelctricity
be less afraid?



Just a wild guess but maybe some sort of built-in surge or over-voltage
suppression?


That or some marketing suit figuring three prongs makes it look more
serious;-)
