In my house there are sockets with grounding (3-pin) and some not. They are so convenient and more aesthetically pleasing than the ones sold at the hardware store. These aren't dark gray squares, they just look more modern and less industrial. No more searching for an extension cord to use a 3-pin plug in a 2-pin space.
