> The point is that GNOME 3 visibly and demonstrably was trying to avoid potential litigation by moving them to the CSD bar at the top.

Well, the buttons in the titlebar at the top are reminiscent of old Windows CE dialog boxes, so I guess they're not really original either! What both Unity and GNOME 3 looks like to me is an honest attempt to immediately lead in "convergence" with mobile touch-based solutions. They first came up in the netbook era where making Linux run out-of-the-box on a market-leading small-screen, perhaps touch-based device was quite easy - a kind of ease we're only now getting back to, in fact.
