Hello, Do you know how Windows (or Mac) created?
I heart that Microsoft steal Apple (MAC Education).
But How Apple created MAC ?
And it is easy to create an operating system ?
It's lot's of work to create an operating system of the magnitude of Window or Macintosh. There other types (such as "embeded" OSs) that are not so much work but the user doesn't get to interact with them very much.
Apple actually went into a Xerox research facility called PARK and "borrowed" many of the ideas for the Mac interface from work that they were doing (the mouse is a prime example, icons on a graphical "desktop" is another). To their credit, Steven Jobs' team packed those ideas into a person computer and sold it at an affordable price. The Xerox project was running on a mainframe at that time.
