What is the best way to turn the screen and touch input off with the power button? I am looking for the power button to act like a tablet or a smartphone. It is surprising the option to turn off the screen by pushing the power button is not an option in the advanced power options. This would make the Surface a lot more practical as a tablet. Turning the screen off after "x" minutes is not really helpful because the touch input is still enabled and in practical use, you want to turn the screen off and walk to the other room, listening to music etc. immediately, not after the screen has timed out. This would also conserve battery.
