There is a reason that the old saying is "reduce, reuse, recycle". The effectiveness is in that order: reduce consumption, reuse what you have, and recycle what you can no longer use.

There is a very straightforward opportunity here for Apple to enable "reuse". They absolutely should be doing that.

Can you name an example of an AIO (or laptop) usable as a display?

I can't even name one other than an iMac that I would want to use. The whole reason to want to use the older 27" 5k iMac is that it's an incredible display. Better than you can buy, other than the 27" Apple Studio Display.
