Sistertech had a client a few days ago who was having trouble with her wireless keyboard and mouse. It was a Logitech Cordless Desktop LX 710 Laser. Usually they’re pretty stable. Poor thing. I have observed first hand how volatile humans are when their computers and peripherals fail them. Have you ever heard such language? Such sniping and snapping? Very unseemly, really. As a precaution, I made a note of the client’s condition in my Service Call book as by the time Sistertech arrived on site, the client was extremely unquiet.
