My friend running Ubuntu just called me saying: "my screen got flipped, how to fix it?"
I told him how to fix it but that raises the question, why is it possible to flip the screen? On Linux you could flip the screen, on windows you could make it rotate sideways.
I can't think of any reason that would make the feature useful, if you want to rotate a picture you could do that in the image viewer.
What type of users flip their Linux or Windows screens? For whom is this feature created?
