> Another way of wording that would have been to say that window manipulation (including scroll and resize) have always existed on the right side of the window and moving some of those controls to the left is not only a flaw in Unity, but in OSX as well.

As GP explained, it plays well with systray icons which have been on the right for a long time. There is only one bar to use(or use extra screen space) and I would rather have systray untouched.
