The iPad has an in-built Maps app on the Home screen that is integrated with Google Maps. If you have a 3G iPad, which has built-in GPS, then this Maps app will show you your position. But, even without it, you can navigate around the world using Google Maps and select whether you want to see the satellite view too. In addition, you can enter your destination - either by zip or postal code, or using a 'pin' dropped at the location you're viewing on the map, and the app will give you directions as to how to get there. It's integrated with Google Street View too so, rather bizarrely, you can see (in Street View) where you actually are from GPS. Great fun...
