Apple Maps is gorgeous, I love using their navigation system. However, it has a huge problem: it has wrong locations. It is missing a lot of basic places like restaurants, but fundamentally it can take you to the wrong city.
I was going to a meeting in Palo Alto, and the app listed a Hawthorne address both in Palo Alto and in Los Altos. I select the Palo Alto one, however, it instead takes me to an address in Los Altos near the Palo Alto border, nowhere near the real Palo Alto address.
This will cause huge problems when it launches, given that hundreds of millions of people have iOS devices. It will cause huge problems and people will revolt and want Google Maps back. Apple invested a lot in design, but they are missing the quality utility element which is a key part of Google's philosophy and expertise.
