We do, but that doesn't help you much if e.g. they have two computer systems plugged into the same double socket outlet and you want to seize both of them without powering them off, or you fear that the computer system plugged into one socket will react badly to the loss of power of whatever device is plugged into the other one alongside it. Almost all of our sockets are also switched, so you're playing with fire every time you put your hands on it -- you might knock the switch and kill the power to that socket just by trying to take it off of the wall.
