Google Earth

Not too long ago a device like the iPad that just ran something like Google Earth would have been worth a small fortune. Now you can add Google Earth to your iPad for free. It works as you might expect, allowing you to zoom in and around the planet looking at satellite imagery, photos and information. You can get a lot of education and entertainment from this app, and kill a lot of time. This app has been around for the iPhone for a while, but the new version adds native iPad viewing as well.
