I use GPS at times (sometimes heavily), and don't mean to insult anyone and their preferences, but maps really put your whole route, surroundings, and the world in complete perspective, while GPS puts major blinders on (my wife and I outright say GPS makes us, well, you know). May road maps live forever! I love them so much, I have vintage U.S. and European road maps prominently in my antique business inventory. I have always gone with the inexpensive promotional big box store versions of atlases(KMart, Walmart, etc.). I like the idea of spiral, a major positive feature. I have gone so far as cutting a few pages out and putting them in plastic sleeves for a specific trip, when that helps keep packing light.
