Windows er jo egentlig en kopi av Apple sitt OS på mange måter, så om vi ikke hadde hatt Apple så er det ikke sikkert Windows hadde vært som det er idag.

Steve Jobs visited Xerox PARC in 1979. He was excited by the revolutionary mouse-driven GUI of the Xerox Alto and was keen to use these ideas back at Apple. By late 1979, Jobs successfully negotiated with Xerox for his Lisa team to receive two demonstrations of ongoing research projects at Xerox PARC; when the Apple team saw the demonstration of the Alto computer they were able to see in action the basic elements of what constituted a workable GUI. A great deal of work was put into making the graphical interface into a mainstream commercial product by the Lisa team.
