This is the globe that you always wished you had! Spin it with your fingers, zoom all the way in to be able to see the car in your driveway, turn roads, labels and boundaries on or off. There even are tours of interesting areas, 3D flyovers, and photos and data that users have added. Google Earth is a "must-have" first app for anyone who loves armchair exploration. Many companies and agencies use the Pro version of Google Earth for things like city planning and route development.
Skype lets you talk to other Skype users, anywhere in the world, by video, audio or instant message at no charge. You can also use Skype to call landlines or cellphones anywhere in the world, on either a pay-as-you-go basis (buy some credit and buy more if/when it runs out) or by subscription. It's available for almost every computer and mobile platform except ChromeOS (Chromebooks).
