Traveling lightly is important to frequent travelers, and the easiest way to economize your luggage is to utilize the mobile tech you already own.
Think for a second. Your smartphone can replace a calendar, airline ticket, watch, music player, camera, video recorder, notebook, GPS/map, flashlight, book, and even a payment method (in some cases). Oh, and I suppose it works as a phone as well. Add apps and you’ll hold the world in the palm of your hand. Use Uber to get a ride to your hotel or Foursquare to find the greatest restaurants nearby.
