Enhance your travelling experiance? Then ditch all that crap. You do not need a smart phone. All it does is help you isolate isolate yourself from the world around you.

See the world, converse with the natives and eat their wierd food. Don't get bogged down lolling memetweets to your facewall on bebosquare, you can do that at home for free.

Anything you NEED you will find where ever you are at.
