This is a trick question. The desktop and mouse are not part of the operating system they are hardware but apple is the only system that uses a one button mouse. The GUI and finder feature are proprietary to apple but the apple operating system is built on top of the unix operating system similar to Linux and other systems do have similar features/interfaces with different names. If the question was what sets apple systems apart from others I would say the mouse.

model vehicles use different sizes. These tubes are often color-coded for easy
identification.
