And what even smaller percentage of people go through the trouble of reporting an error event if they do see the curl? It feels weird to pay for a service, and then have to actively work to make it better.. (by paying, I mean buying an ios device..).
Then I understand the release and iterate strategy, and I'm sure it applies in many situations. But when you are Apple and have painfully built a reputation of releasing only great products, you may want to think more than twice before crippling your star product, even if it's just a little.
As these threads have demonstrated, I think a segment of the population is actually highly interested in accurate maps.
Weird as it sounds (not being sarcastic), I think people will actually report problems, especially in their own neighborhoods or places where they travel and know well.
The problem for Apple is, they'll get a bug report something like:
Your maps is rubbish, I couldn't find the park, where is streetview too!
They will then have to have someone look at that data, try to find the area, a park nearby, compare with whatever licensed satellite data they have, and try to redraw that section, or they have to request new data from tomtom, wait a year, and hope it is fixed. That is a huge task, and not one I'm confident Apple will ever manage to pull off. The satellite data they have put into the app is appalling so if they try to use that as a reference...
And that's for the 0.5% of people who bother to report a problem - the rest will just lower their opinion of Apple and look at other solutions next time they're shopping for a device.
