Tiling window util for big monitors on windows

For those of you who use a wide-screen monitor, managing windows can be a bit annoying. oh for a tiling window manager for windows! ah well, this is nearly as good: it maps Ctrl+Alt+numeric keypad such that the current window snaps to the relevant half or quarter of the screen. makes it very easy to quickly organise your windows into tiles, without having to touch the mouse (as you do with windows 7 new features).
