Keyboard, video, mouse - the three items that every computer needs to interact with a living being. However, what if you have two or more computers, and only have room for one set of these I/O devices? Enter the KVM switch - plug all three into a small box, and plug extra leads into each machine. Ideally, this was an expensive but cost-effective solution for server administrators, but lately KVMs have appeared for the home-office/enthusiast market. The USB Pocket KVM Switch throws-in USB switching in the event your keyboard or mouse does not have a PS/2 port.
