It reminds me of discussions around Mac vs PC in the early days. The experience of using a Mac was more "fluid" than Windows. The Mac would draw windows faster, move the mouse faster (as in more refreshes of the cursor position per second) and that made it more comfortable to use. At the same time I also used Sun and SGI boxes regularly and the stark difference between the jerky mouse movement of the Sun and the fluid, Mac-like, movement of the SGI made the former an inferior experience (even though I liked OpenWindows over SGI's window manager whose name I forgot).
I'd love to have wobbly windows back.
