and (b) didn't mean anything to anyone you were trying to appeal to?

Look at a keyboard with fresh eyes, and it's complete gibberish. What
does ctrl mean? Alt? Esc? What do all those F keys do? Why does that
little key say "Delete" on it, when I use that big key with the arrow
to actually delete thing?

Of course, since then, the Mac has inherited lots of other interface
conventions, largely from the NeXTSTEP world. It's lost some of its
puritanical consistency (why is there what amounts to a subset of the
File menu on a pop-up "Action" button on the top of every Finder
window, for example. And what the heck is the "Library" folder - it
makes sense to me, but imagine you're someone who's never used any
kind of Unix before... is it where you store eBooks?).
