Do GPS’s work for you?

Thomas Hawk and Kent Newsome are talking about GPS’s: Kent reviewed one (an expensive Garmin unit), and Thomas added his experiences and asked “do any work for you?” I don’t use one much, but I have Streets and Trips setup with the GPS for our road trips and they are fairly good to use. But fumbling with a laptop in your car isn’t as safe as dealing with a device that was made for that purpose.
