Future Vision by Erwin Van Lun on this article
You take your friends list everywhere. Currently you have to copy it, but later you’ll indicate who you are, which social networks you’re on and your friends will appear automatically and you can call them with a press of a button, text them, IM them, play games, whatever. And when you meet a new friend you add them to your mobile and they’ll be available on another mobile or tv or wristwatch too. This’ll need a little more time, but not much longer.
