The problem with crowdsourced bugfinding is that it goes against Apples philosophies completely, and Im amazed at how the cognitive dissonance has caused peoples opinions to change so rapidly. Apple was always the "Well released it when its ready" company, and the new Maps seems to show the exact opposite.
Does nobody remember the downsides of on-unit turn-by-turn navigation? Does nobody remember the complete decimation of TomTom and other GPS device manufacturers after the advent of smartphones? All of those downsides still apply, but now that Apple has rolled out their new solution, everyone thinks its the best thing since sliced bread.
Not to mention, this solution screams of outright cheapness and laziness. Rather than negotiate the use of Googles more advanced APIs and provide their customers with the very best mapping solution while they worked on their own, they decided that the consumer should work out the bugs for themselves and become their own cartographer. In densely packed cities, mapping is key, especially when finding meeting places, restaurants, or events. There can be almost no margin for error.
This seems to show, more than anything, Apples first step on its slide to mediocrity without Steve behind the wheel.
