That said, I've been using the Apple supplied Maps app for the past couple months, and I don't see what all the fuss was about. The turn-by-turn voice instructions have proven a boon, and they haven't guided me off course once. They're sometimes slow to recalculate when I stray from the plan, but the old app didn't automatically recalculate at all. (Or provide turn-by-turn voice instructions.)
Yeah, I know the data behind Apple's app is reportedly better in Seattle than it is in a lot of other cities. But I live in Seattle. So it's been fine. Different, but fine. And certainly a helluva a lot better than the nothing we had before we all got smartphones.
