One of my favorite features of Google Maps is the one-finger zoom: Tap anywhere on the map and then make the scroll guesture (it feels like a double-tap, but the second tap is a swipe up or down guesture instead). Because I usually operate my phone with one hand only the "pinch-to-zoom" guesture is just a pain (especially when you're carrying something in the other hand) and zoom buttons are easy to miss (e.g. while walking). This guesture also works to zoom in and out in Google Chrome, yet I don't think I've seen it in the Apple world yet (except of course in products made by Google for Apple devices).
