Choose any place in the world and view it perfectly from above, then choose another place and travel as if you were flying over all the cities between those two localizations.
It's amazing, and it's being improved day by day. Now it also includes 3D cities, but that's not as stunning as viewing the streets with the options Google Street View which places you in the middle of the street viewing the real images of the streets included (which are more and more day by day).
The layer system allows you to know a lot about the places you desire: hotels, restaurants, petrol stations, hospitals, monuments... You can use Google Earth to know the distance between two points or to get directions.
Google Earth can be used for a lot of purposes. It also features information from Wikipedia or Panoramio, which means you can access information from different locations and photos uploaded by users.
