You think only 1 out of 100 posters on AppleInsider have used iOS 6? I'd say that even among iPhone users that percentage is likely higher and that on AI the number is much, much higher. I'm certainly using iOS 6 on all devices and I can say that in the ways that I want Maps to work the Google-free version is ultimately inferior. It wasn't until beta 3 that my iPad (3) Maps felt fast, smooth, and wasn't crashing much. As of beta 4 my iPhone 4 Maps is now decent — not good, but decent. I'm still missing Street View and still have no use for FlyOver.
I haven't yet upgraded to Beta 4 and Maps is of hardly any use to me in India right now. However, I did a quick view of 1 Infinite Loop on the iOS 6 Maps on my 4S and the maximum zoom did provide a pretty detailed (though elevated) view of the street. I have never seen Street View in action, but as Dick Applebaum did say, what I saw with iOS 6 Maps did seem like a good approximation of Street View.
Still, I must admit that Maps may be the one thing that will be deried to no end when iOS 6 and the new iPhone are released. I think Apple are aware of this and they really do not have a choice. If they want to keep Maps in-house, they need to use the iOS user-base to feed them the data for some time till it works well.
