The new maps load 100 times faster because instead of downloading the entire map image for each level, the app downloads meta data which describes the entire map at all different levels and then renders the appropriate sector on the fly. This will start to give Google Maps offline capabilities on mobile phones. It may be possible to cache a map of an entire city on the phone. And for people who use the turn-by-turn navigation in Google Maps, when the new app comes out it will be able to recalculate the route even without a data connection.
The Google Maps app will also use the built-in compass on Android phones to automatically flip the orientation of the map to the person holding the phone. That orientation feature will come in handy when you are coming out of a subway station in an unfamiliar stop, or exiting a building.
