It's neat to be in control of four different computers (one a Mac) with the same keyboard/mouse.

All using different means to do so (though not all at the same time, of course). One, the Mac, is controlled using Synergy. Another, which isn't even on the same desk as the other three, is controlled using TightVNC. And the third is controlled using a switcher box. The last is the most annoying of the three, because it requires actually reaching up to the switcher box and pressing a button.
