The Mouse Turns 40

Link to December 9 MaximumPC post, "The Mouse Turns 40, Still Best with At Least 2 Buttons".

Excerpt:
It's hard to imagine, but the computer mouse celebrates its 40th birthday today, making the rodent susceptible to premature over the hill jokes. The one-button wooden mouse, which was built by Bill English, was first used by Douglas Engelbart on this day 40 years ago in a demonstration at the Fall Joint Computer Conference (FJCC). Dr. Engelbart showed how the new input device could be used to clip text files, copy and paste, and how it could come in handy on computer networks.
