Staring at the pictures in National Geographic or watching the travels on its cable channel has a way of making us want to sell all of our possessions and catch the next plane to whatever far-flung locale they're profiling. A more practical and interactive option now is the iPad app National Geographic Adventure Presents The Greatest Stories Ever Told ($2). Featuring explorers in their journeys around the world, the app includes video and high definition photography, taking you right into the heart of the experience.
Armchair travelers, adrenaline junkies, and natural science enthusiasts can get their kicks watching in-app content, including the sunken Titanic remains and extreme mountain climbing. Cave diving in the far depths of the ocean without buying a plane ticket is definitely what the iPad was made for.
