How can you take a OSX as an example of how it's done and lambast Gnome after the new Safari redesign throws OSX conventions through the window (much like iTunes and other OSX programs have done already, independently "reimagining" how the OSX title/control bar should work in a way that is not consistent at all).
The position of the window resizing buttons is entirely irrelevant when using keyboards shortcuts to control window layout is just much better.
