Google Earth lets you do smooth sailing flybyes of the entire Earth. You can easily fly to any spot on the globe, by entering any associated data, like street addresses, place names or lat/long coordinates. There are overlays that put additional information on the map, like roads, international boundaries, terrain, 3D buildings, crime statistics, schools, stadiums, any number of interesting stuff. You can do Local searches in the program, with icons on the map and a display on the side showing your results.
You can leave notes, called "placemarks" all over the map, so you can remember where all sorts of places are. Searches and placemarks can be saved as bookmarks in "My Places". Everything can be output in an XML format called KML, that will allow the vast popularity of Google Maps to continue in Earth. You can also email a JPEG of the map, or send a KMZ file if you know the recipient has Earth installed.

Version 4.3 offers up revamped navigation controls, 3-D photo-realistic buildings in major cities, and time-lapse views of sunsets and sunrises. Also new in Google Earth 4.3 is access to the street view movies found in Google Maps. Just click any of the camera icons and the familiar street view window will pop up. The sunrise and sunset movies are also quite impressive. Fly to a location you'd like to see and click the "sun" button in the toolbar. That will bring up a small timeline graphic and you can either hit play or drag the timeline slider to watch the day unfold.
