Not only that, but a phone solves the "where am I" problem, which was such a pain when I was younger. Having to look for the nearest street signs while driving around, barely being able to read them and guessing its suffix, then searching the map index for which coordinate that street is in. Basically all problems solved by GPS. The directions feature you pointed out is basically a whole other application (replacing printing mapquest or written directions).
