David Gelernter, Yale professor of computer science, says above all things Steve Job was designer-in-chief. At his Stanford commencement address in 2004, Jobs recounts his experience in a calligraphy course at Reed College as one of the singularly important experiences of his life, and something he carried over to the the revolution in portable devices- portable Macs, iPod, IPhone and iPad. The search for and building of elegant, easy to work, fun to use devices. Job was able to grasp the potential of such devices, says Gelertner, from his very first visit to the Xerox research labs in Palo Alto in 1979. In doing this he gives credit for long forgotten pioneers of the personal computer, who were just as important perhaps even more so, Douglas Engelbart and Alan Kay. At Xerox, Kay built on the earlier innovations of Engelbart. Engelbart was first to develop the mouse, onscreen window, and the concept of computers doing more than just computing, such as controlling machinery, doing everyday stuff, and doing things with pictures. Xerox's corporate executives failed to grasp the significance of the developments in their labs. Jobs grasped this rightaway and put all his efforts into developing the Apple Macintosh in 1984 incorporating these ideas. A decade later Gates copied the Mac's eay to use features and created economies of scale, creating the personal computer that we know today. The internet was a parallel development during that decade after the pioneering work of Tim Berners-Lee on the worldwide web. Jobs took the experience one step further and created new devices like the iPhone and the iPad that brought mobility, ease, and refinement to the internet experience....
