To be fair I don't think copied is the correct word. Like 3D flyover for example. Google had this for a while before Apple in the Google earth app. But to make a world class mapping system (like I'm sure Apple wants) something like this is almost basic functionality. So while some say its a copy I feel its just something that had to be done.
I use the word copy as more of an insult. Like the notification center in iOS, I hate it. It constantly blocks me from using the back button in many apps and turning it off is just as bad of an option. I feel that's a copy and poorly integrated at that.
Or when Apple was suing for slide to unlock and at the exact same time added camera from the lock screen. Granted I think they did a decent job at that but I was using vanilla android devices that had that feature. I consider that copying just based on timing.
3D flyover is a gimmick. It has no bearing on navigation whatsoever. If a city doesn't have 3D flyover for it in either Apple's Maps or Google Maps, you can still get turn by turn navigation, right? 3D flyover is cool to look at, but after a second or two, you just say meh, like I did.
