At work, I'm lucky enough to have available Microsoft site licenses for most Microsoft software, including the various operating systems.
I've grown to appreciate the Windows 7 hotkeys for window management, Win + up/down/left/right, that allows hotkey access to moving a window amongst multiple monitors.
However, my home machine is still running Win XP, and I've always felt greatly handicapped (productivity wise) in having to reach for the mouse to move windows around.
No longer. I recently found Easymon (http://www.codessentials.com/products/easymon.html), which is a small, free application that allows almost identical functionality.
No more reaching for the mouse! :)
