Have to agree with Art here. GPS has really made life a lot easier in many ways. But as with most things in life, it shouldn't be taken for granted.

Right now, GPS is pretty much the only gamer in town. GLONASS, Galileo etc. all sound great, but they don't WORK just yet. Even once the system is set up it will take a while to sort out the glitches and make it economically viable.
