I have a friend that can't use a map for anything but starting a fire, and I'm not even sure he use one to do that. I have tried to show him the simplest uses of a compass, and the only thing he understands is that one side of the needle points north. Ok he honestly isn't that bad but he cannot use a compass or a topo map. Give him a GPS and he does ok and can generly find his way around. He and some folks like him cannot grasp the use of the compass and map so for them the GPS is the right way to go. He is resposible enough to know his limitations and works within them.
