How useful is a GPS?
I am debating whether to get a GPS. Can anyone tell me how helpful they really are (say for a USA to Argentia trip)? I have done Mexico and Costa Rica with paper maps with no problem. And I'm getting fed up with the whole digitial age too -- do i really need to take a digicam, cell phone, MP3 player, and GPS. I am travelling to see the world, not a small LCD screen. And I won't venture too far from paved roads. So would the GPS just be another gadget, or a practical tool for navigation?
