I find that, at least for walking extended distances over unfamiliar territory (I can't drive), having the map is very useful. Not directions, not routing, but at least a map so that I know where point A and point B are, and I can see the possible routes between them. It also helps when mass transit stops are on the map. Digital mapping is a great boon to my travel, because it's so much easier to look at and carry a 9 inch tablet than to have to haul paper maps. If I didn't have clear digital mapping available on my devices, I probably wouldn't go anywhere new because it'd make me a target for either crime or scams. Now, as far as routing... I like looking up directions before I go so that I have a rough idea of where I should go. But I don't use GPS-backed directions en route most of the time.
