The idea of a wireless keyboard and mouse combination was once thought of as problematic and unreliable. But technology has changed much since companies such as Logitech and Apple made wireless keyboards and mice more practical and less expensive. In fact, serious computer users cannot live without a wireless keyboard or mouse to do their work.
First, anyone who has worked on a desktop knows how wires can either take up desk space or get tangled underneath, which is especially annoying when you are trying to figure out what wire is connected to what. A wireless keyboard and mouse has no wires so they are out of your way when working and there are no cord issues to worry about.
