In addition to pause/play music, the middle button on the iPhone headset has several functions like skipping tracks, answering phones, activating Siri etc.
Apple didn't invent the mouse. It was built at SRI International by Douglas Engelbart and patented in 1970. Apple licensed it for about $40,000. Also, Apple wasn't the first company to attach a mouse to a computer. This had been done by Xerox on their 8010 Star personal computer, which unfortunately wasn't a success probably because of its steep price, a staggering $16,000. In addition to being the inventor of modern mouse, Douglas Engelbart is best remembered for giving a live demonstration of several computer technologies at the Fall Joint Computer Conference in San Francisco. This Mother of All Demos took place on 9th December 1968 and showcased windows, hypertext, graphics, video conferencing, word processing and, of course, the mouse.Mother of All Demos video on YouTube [more...]
