In the 1970s, Xerox was working on its Alto line (the YOU KNOW, FOR KIDS revolutionary machine from which Apple would steal its The notion of portable computing dates back to the early graphical user interface and mouse), but the company shied days of computing itself. Pioneering nerds may not have had away from a portable, mainly because no one else was doing it.
