[link|http://synergy2.sourceforge.net/home.html|Synergy Software KVM] is one of those rare things that made me exclaim,"HOW did I get along without this for so long?"

If you run multiple computers on your desktop and are constantly switching a KVM or are using multiple keyboards, mice, etc. - you owe it to yourself to check it out. Works with Mac OS X, Winders, and X11.
