I think you're glossing over things. How to use a mouse. The difference between moving your mouse cursor and focusing a text field. How to double click. (most new mouse users have trouble with this) How to turn the machine on and off. Clipboard. I don't have much experience with non-Windows OSes, so I won't comment on that. But everything inside a computer is necessarily more abstract than a door handle, since it doesn't physically exist. IMO that makes it harder to understand necessarily.
