They had no real GUI in the 70ies, it was a terminal with mouse control. The GUI comes at the end of the 70ies, beginning 80ies and the guys from Apple came over, at that time, to see the concepts and prototyps.

From there, they started their own GUI metaphor.

I like the part in the video, when the guy inserts this big magnetic storage :D

As for Apple, the kernel is open source, but the whole Cocoa layer is closed. As for Android everything must be open, apart from the Google applications. Or not?
