You can believe what you want when it comes to military satellites. Not gonna force the issue, but let's just say I was personally involved in this particular field for several years. Public information regarding what our govt can or can't do, may or may not be fact. But I'm glad you believe that we can't target something down to the centimeter.

Possibly. Except in one crucial area; Street View. This is a very time consuming and costly thing, that Apple is years and years behind on.
Street View is not that useful. It's fine when you sit at a desk and try to browse the streets but it's not practical when you actually use for navigation. In term of sitting at the desk, I find fly over and 3D mapping on Apple map superior than street view. It gives me a true interactive experience instead of a static 2d point and click like street view.
