GPS in your chest pack, compass around your neck, map in a ziplock in your pocket. They all have a role. A map/compass is handy for making sure you are heading in the right direction especially when you can see landmarks. But GPS can save you a lot of screwing around, and you don't have to leave ribbon trails like the old timers did in trough country where taking a slight wrong turn can mean going down the wrong drainage and a lot of extra hiking and effort. I find old ribbon trails all over the place coming off of mountains, but I'm not into marking up the landscape like that.
