Dick says that while it's been around for awhile, he just got an IOGEAR 2 Port USB Cable KVM Switch with Audio and Mic connections. He uses it to switch between computers and still use the same monitor and keyboard. Leo says he's used them for years and they just plain work! Dick says it took five minutes to install. There are no additional cables or software needed. You don’t need a power supply either; it’s just plug & play. It's $26, or $17 without the audio connection.
