I explored this concept a bit. What if we could detach our keyboard from our computer, and connect it to another one? By doing this, we'd be automatically carrying our settings, wallpaper, interface and a group of personal files, making it our own instantly. On a school environment, for example, this would be very useful to share documents between students, and allow them to work on other computers without needing to get used to different interfaces. It would work like an extension of their own computer.

Imagine plugging your keyboard on another PC and automatically seeing your own browser bookmarks, your OS settings, your Illustrator settings, etc., just as you left them on your own machine.
