I recent thread here got me interested in GPS-based travel computers. They sound like fun gadgets, but having never used one I'm not sure they are actually all that helpful. Since we'll be hitting the road pretty soon we thought it might be useful to have, say, a Garmin Nuvi--if they actually do anything worthwhile. If you use one, what exactly do you use it for, and is it worth the rather steep price of these units?
Thanks,
Don
