Just a coincidence, but I have the same Linksys KVM switch that Breaker78 mentioned. It's very convenient to use for switching between computers (tap CTRL twice), and has some other neat features. But there are somethings I noticed that bother me. I noticed slightly faded colors when routing my monitor through the box for my 2 computer (now I just use the separate HD15 and BNC inputs on the monitor). Another thing, I use the SHIFT key for certain actions in games (like jump or walk), and SHIFT also happens to be a key that the Linksys KVM monitors for switch commands, so there's roughly a half second delay between pressing the key and the computer actually seeing the keypress. This isn't good for me in games like Tribes, so now I have to sell the KVM and get a different brand if the key-switching can't be disabled. 😛
