I think cycling is a particularly good example of this. Using the phone on a mount for navigation can help you go more interesting places you're less familiar with, but you have to look at your surroundings to be vaguely safe. I don't cycle with music or anything, I don't think I'd feel safe doing that but I really enjoy a long cycle with the phone on a mount for directions.

A garmin or something would likely be better for this, but I don't particularly want to buy one and the phone does a fine job.
