I still don't really know if my 2013 MBP is starting to belong on this subforum or not, it
is a retina model, and AFAIK last time those didn't belong to early Intel, but the thing is now 11 years old and a real trooper.
And it's for some reason faster than my 2017 Touchbar MBP. I think that's due to its probably failing SSD, because that machine takes like half an hour to boot Sequoia, it also doesn't charge anymore (but firmware throttling is disabled).

So this 2013 MBP now serves as a little backup not taking + acting as a second screen by using Universal Control, which works very well with my M2 Pro mac mini as a host.
On the road I just use my Framework, but I do kind of miss the whole ecosystem, KDE Connect works well enough, but is nowhere near as close to Apple's offering.
EDIT: I see people mentioning their old monitors, my iiyama you see on my desk is from 2007

I've been using it continuously since 2012 when I bought it from someone who probably also used it full time.
