Wow. Amazing so many people can be so wide of the mark - Dan Crow's article for the Guardian being the exemplar. That said there's a lot of sense spoken in these comments too.

Maps.app moving away from Google was vital and not a punt made on a whim. A move of this magnitude is always going to have teething troubles and the only thing borked in Maps.app is some of the POI data, everything else is an improvement (even Nokia have their own 3D maps over at Here) Street View is yesterday's tech. Siri isn't the shit heap some like to make out either. Most of it's troubles are down to the fact that it relies on crappy telco networks to communicate with the mothership. Google's new voice search on iOS is often very very flaky indeed. All in all, when it comes to Apple, people seem to have very short memories and very unrealistic expectations, oh and they also seem to forget that the company is and has been outperforming everyone else with the same simple yet effective formula it's been using for years and years...
