With each search engine trying to out do each other they are creating great products. But leave it to the users to make them even better. For example, Flash Earth.
Flash Earth takes information from Google & MSN satellite maps and allows the user to smoothly zoom in and out, switch map services and waste a lot of time. It’s quite fun to play with!
Here is one tip to keep in mind. If you are looking for a specific place on the map, use the MSN with labels first, then switch back to the Google on if you wish. Labels make it much easier to find areas.
