This is the mode how I run Windows with WinSplit Revolution. It doesn't change anything by default, but with alt-keypad I move certain windows to the upper left, upper right, bottom right, bottom left and so most open applications have their exact position, but everything else is floating. I guess I'd use a full blown tiling WM if there was one, though, I don't really see any downsides once you configured it to your preference. So bad for new machines, good for regular use. (for me).
