You're right, I should have said "still don't have on PC". I believe Xerox Star also had all those keys and then some. This might not seem like a big deal for some. But there are two important points to consider: 1. A lot of inexperienced user still go to mouse menu for copy-paste. This is horrible, but kind of natural, since a lot of UIs don't teach shortcuts. 2. Cut/Copy/Paste/Undo/Redo should be treated as fundamental building blocks of user interaction, not some "shortcut" that happens to do a thing. They aren't even UI-specific. You can do all of them in a command line app (although the semantics would much poorer). When I saw the demo of Xerox Star on YouTube I was both enlightened and depressed by the current state of things. Most people have no idea that icons were supposed to be objects and that interacting with them was supposed to be a way to send and direct messages to and between them.
