My favorite – and fancy ($50) – Logitech wireless mouse has inexplicably run into trouble with my new computer. So now I’m packing the $10 wired mouse for my work week. I’m a mouse guy : no touch screen or touch pad for me, thank you very much. And check out the ‘mouse house’ that the scientists working at the CERN Hadron Collider has set up for old retired mice. (The Large Hadron Collider is starting up again after two years). Time to smash some particles again!
