I used to chase down xfce, lxde, openbox,etc to find the best light weight WM for me, problem nowadays is that, I need chrome on all of them, whose memory usage alone overshadows all those windows managers. unless chrome can somehow run in, say, 200MB of RAM, the windows manager are no longer that important to me on the resource consumption side.
