And this, more than anything else, outlines Apple’s biggest hurdle: people keep finding mistakes in Maps because looking for them has almost become a sport. When was the last time that you saw users analyzing Google Maps with this ridiculous level of detail? Had Apple set the public’s expectations better, we may be having a very different discussion at this point.

This pretty much mirrors my own experiences here in Toronto. Further, I haven’t been looking for mistakes, per se, but those few I’ve encountered have generally been about the same in both iOS 5 and iOS 6 — even to the point of some of the same wrong/closed locations showing up in local search results.
