- Apple didn't invent the status bar. It's a sort of bastardized son of NeXTSTEP dockbar that all operating systems rapidly took ever since. Apple first status bar only appeared with System 7 in 1991. And it was just a small extension to the original Menu bar that also displayed the hour and time of day on the far right.
- Apple didn't invent the mouse. Xerox did.
- Apple didn't invent the concept of windows. Xerox did.
