I dont know any private person in my circle that actually sold their laptop until it wasnt broken or so painfully old that the used value was mostly for spare parts. That may change a bit with the skyrocketing pc part prices but still.

This used to be case before the M series. Now each year a new M processor gets released that are "cheaper" than the previous generation MAC - better processor, more RAM and more storage for similar price than last year model. This impacted their price in used market.

My main computer is a 2020 m1 Mac. It handles everything I throw at it. I predict I’ll upgrade in maybe 4-5 years.
