* Google Maps, bookmarked on your home screen, can be particularly useful to people who use public transit. You can enter the time you want to depart or arrive at your destination, and it will give you several mass-transit routing options, plus estimate how much time the journey will take and what it will cost compared to driving. But you don't get spoken directions.
* Nokia Maps, which you can also bookmark and use like an app, provides car, walking and public transit directions (without spoken guidance). Unfortunately, the transit directions don't estimate how much time or money the trip will require.
