The first graphical interface was invented by Xerox at PARC. The machine was called the Alto.
I don’t think Jobs ever said he invented the GUI. Or the mouse. He did “rip them off”.
As far as Apple goes today Mac OS X is built on BSD. Which is a POSIX compliant unix OS. Jobs did not invent Unix, that is for sure:)
Jobs scabbed other peoples work too. But in a much prettier way than Gates...
