Re: Performance? Art?
Depends where you are and what you are doing. I know many people who use a satnav on a daily commute as much for delay notifications as anything else. In my case, I'm doing fairly long trips with occasional detours around problems, not always to places I'm families with, but I still set the destination for trips I do regularly so I have an ETA if the boss calls and can re-route around traffic "incidents" in areas where I only know the major roads.
