No. To mention a few, Xerox had a verb-object interface (you selected 'Copy', selected what to copy and then where to copy it), not the object-verb one, didn't have the concept of dragging, didn't automatically repaint partially uncovered Windows, didn't have a laptop with a keyboard that's close to the screen so that you can use your palms to prevent it from falling from your lap, and didn't do a click wheel or a touch screen. Xerox also, AFAIK, didn't do a hockey-puck mouse or a phone that bends :-)

What makes you think so?

Okay, I should have said the first significant thing that advanced the state of the art. None of the things you mention, especially the snarky bs, are anywhere near as big, IMHO.
