The Musical Museum in Brentford might take them off your hands. They have a large collection of fully operational and lovingly restored self-playing instruments.

As somebody who recently had to switch to Mac for work, my experience has been the exact opposite of this. Every other OS I've used since Windows 95 I've been able to get to grips with the same way: start off using the mouse to find my way around the UI, and introduce keyboard shortcuts as and when I find them useful. Eventually I get to the point of being able to use either exclusively keyboard or exclusively mouse for most tasks.

MacOS seems to _require_ some unergonomic combination of both from the get go. Some basic things are easy with the keyboard but hard/impossible with the mouse and vice versa. The Finder app doesn't even have a button to go 'up' a directory for god's sake.

Yes but more importantly it's a definition that allows those who wield it to feel as though they are on the right hand side of the 'bell curve meme'.

I think feudalism is a misnomer here. Feudalism is a historiographically messy concept to begin with and many Medievalists reject the term outright. But even if we were to distill it down to some simplistic yet workable definition I still don't think whatever we come up with would be applicable to the present situation without seriously torturing the analogy. 'Rentier capitalism' would be more apt.
