It turns out to be turn-by-turn voice navigation. It wasn't a feature in the original Apple-Google licensing agreement, so Apple went back to Google to renegotiate what has become a top-tier feature on Android. Apple wanted it. In return, Google wanted increased branding in the maps app (Apple refused) or to integrate Latitude (Google's FourSquare competitor), to which Apple refused as well. As a result Apple was forced to seek other sources in order to obtain this feature." Eventually, iOS users who don't want to wait for Apple-Google parity will be able to download a native version of Google's maps (rather than a hacked version), but that could be a ways off.
