> the idea that a server has something one can refer to as “the” screen, or “the” mouse – is completely and utterly wrong

I don't disagree with your point per se but the reality is a little more nuanced that you suggest. For example, UNIX provided green screens to null terminals long before Windows Server was a thing. And mouse enabled Linux / UNIX terminal tools (eg elinks or aptitude) support mouse input even over SSH.

Though I do appreciate you were referring to "monitors" specifically when you discussed "screens", it's still worth noting that the old thin client model of computing has come back into trend again with Windows desktops available in the cloud (typically aimed at organisations that want a managed deployment of workstations - akin to a hosted Windows Terminal Services).

So it really depends on your workloads and what your definition of "screens" are :)
