Comment 793 for bug 532633

The issue here is that most people in the world are right handed. For right handed people, it is much more convenient to move mouse to top right or bottom left. Thus this is where windows controls should be.

I personally feel that the move to shift the button to left was just "APE"ing the mac.

Also I suggest have a default installed interface to switch the position of the controllers rather than having people to use gconf / dconf editor.
