After years of use, our elderly desk top computer needed a new mouse. Robin replaced it with the much newer mouse from our lap top. No problem with that, but then the lap top computer was the one in need of a mouse. So he went out and bought one of those fancy “wireless” ones. This seemed a bit of a misnomer to me. Wireless it may be, but it still needed a plug in contraption, (known as a wireless mouse receiver) that looks surprisingly like another mouse to get the wireless bit to work. The new mouse in the house certainly works well, and Robin is happy with his bit of new technology.
