Maps came in handy, but who is going to fill their trunk with a map for each county or even state? Not me, especially when visiting an area on a one shot. When traveling for show or technical coverage it is worth the few extra bucks to have a GPS unit thrown in your rental. It gets you where you have to go, generally headache free. Some units even reroute you when traffic is detected ahead. Another neat feature is for you enthusiasts that never got around to hooking up your speedometer - most GPS units display MPH. While I'm not suggesting this as a means of detecting speed, it does help. So look how far we've come - no maps, scrounging for change, or asking a fuel attendant (are there any around anymore?). Technology is grand, so jump on the bus and use it to the fullest.
