I will tell you that using Apple Maps for directions while using the watch is great-it knocks on your wrist in one way to alert you that you're going to need to take an action, then it vibrates in a different way to tell you to turn right or left, or continue on straight. Its a small feature but when you're driving someplace busy or walking down an unfamiliar street its really very nice to have this kind of feedback without taking your eyes off the road/sidewalk.
