This is interesting, it sounds like you don't have any first-hand experience with Maps being awful but are advising everyone you know not to upgrade to iOS 6.

Is that correct? I'm not saying it's unreasonable. It isn't the path I'd take though, and I find it a bit surprising.

I'm also curious, you say you have eight iOS devices and won't be upgrading any of them because of Maps. Do you use Maps on all of them? Or is your choice to upgrade none of them more about taking a stand?
