Have a look @ the video and see how cool the Map features are on Android. You can pan around and zoom in and out easily using just your thumb on the touchscreen and while in street view you can just turn around with the phone in your hand and the street view aligns itself to face in that direction. One other thing I noticed was that in the normal view the maps had more detail on on the buildings as shown in the screengrab this is not there on Windows Mobile.
