@MasterPie: Yep, it's mostly small changes that would make a really large difference. It's not just affordances, though. The "edge UI" concept isn't bad, but there has to take into consideration mouse usage in scenarios where Fitt's law doesn't work. Multi-monitor and windowed remote sessions both suffer VERY badly here. A simple solution would be a "button" similar to the Win7 "show desktop" button. Relatively small, unobtrusive, but it gives the necessary visual cues and gives you a hit target large enough for mouse usage in these situations. I expect (read "hope for") these small sort of UI fixes in Blue.
