From a guy who processes thousands of devices in e-waate recycling, legit any refurb lenovo thinkpad/dell precision/hp elitebook laptop. People will stop using tech way before they should be stopped being practically used.
Imo i think thinkpads are better value(due to sheer volume in market) and they tend to have several options (normal laptop vs 2 in 1 vs slim laptop vs big screen vs one with a gpu in it)
