A clock changing time or switching to classic mode on Windows is in no way analogous to the difference between a phone, a desktop and an Xbox. Those systems are substantially different enough to require different methods of user interaction. Do they utilize the same OS at that point? Maybe, depending on definition. But the definition given by pilsetniek specifies UI as part of the OS. So by this definition, No, they cannot use the same OS. "you are bitching because..." Whatever dude.
