Today is the 40th birthday of the computer mouse. There is an excellent story (and video) on the first mouse right here.
So Happy Birthday to my mouse. Over the years I must admit I've taken you for granted. I've let your batteries run dry, I've dropped you on the floor, and I've watched you get abused with remarkably poor design (exhibit A below). I've even tried to banish you into obsolescence with a continuous onslaught of trackballs, trackpads, tablets, and even lowly keyboard shortcuts yet you continue to faithfully serve me as a master with an endless supply of cheese. Happy Birthday Friend!
