Maybe MS thinks that the computer in a future is actually your phone. Then you have different accesories for it. At office you have display, keyboard and mouse.

Maybe MS thinks that the computer in a future is actually your phone. Then you have different accesories for it. At office you have display, keyboard and mouse. The phone automatically senses their presense and atarts to wirelesly communicate with them, i.e. bringing metroless desktop to those peripheals. Then you might have tablet like dummy screen that communicates wirelessly with the phone bringing metrolook to the screen. And you could also use the phone as is with metro. It could easily hook to your home entertainment too. Yes, this is fuuristic, and it is not going to happen soon.
