A new major version of Google Earth doesn't happen everyday, explore the world with tour guide and 3D imagery in Google Earth 7.
From the announcement: "A few months ago, we announced Google Earth for mobile, which offered new ways to see cities in 3D and a new tour guide feature to help you discover places of interest on the go. Starting today, you can get both of those features on a bigger screen that makes it even easier to explore by downloading Google Earth 7 on your desktop. Check out the comprehensive and accurate tours of more than 11,000 popular sites around the world, including our growing list of cities where new 3D imagery is available."
