Believe J.J. Cale, because he knows what he’s talking about: traveling light is the only way to fly. The next time you’re tempted to overpack, remember to take half as many clothes, twice as much money, and your iPad, iPhone, or iPod touch. An iOS device can replace paper maps, books, and travel guides; and the information you’ll find in apps and iBooks is more timely and relevant anyway. Obviously you won’t need CDs or a portable DVD player -- or pricey hotel or in-flight pay-per-view -- to stay entertained. And by posting photos or blog updates about your vacation online, you won’t even have to send postcards. To prepare you and your electronic travel buddy to hit the road, we found the best apps, gear, and know-how to keep you connected.
