If you've ever found yourself switching between two computing devices, such as a home desktop and a work-issued laptop, then you've probably felt the pain of jumping back and forth between two keyboards and two different screens. KVM switches make that process painless. Unlike a dock, a KVM switch remains plugged into both your computers all the time. You don't need to mess with cables. Just press a button on the switch to swap your peripherals from computer #1 to computer #2.
Basic KVM switches have two to four USB ports and let you share a keyboard and mouse, a printer, a USB thumb drive, a webcam and headset, or other peripherals. If you want to share an external hard drive between two computers for backing up or transferring data, a USB KVM switch can help with that too, though you'll often need to plug either the drive or the switch into a power source. More expensive KVM switches will allow you to connect two computers (or a computer and a gaming console) to one display.
This list of KVM switches runs the gamut from simple to full-featured. If you regularly need to swap between two devices, you'll be amazed by how these little devices make your life easier.
