Anecdotally, my path was 2010 macbook pro -> 2015 macbook pro -> 2021 M1, with each device lasting about 10 years, and keeping 2 in flight at once. The 2015 one is showing it's age, and is likely to be replaced this year or next. Running linux on it isn't an option due to all the nonsense involved in suspend/sleep and the effect it has on battery life.

I also have a 2007 Intel mac with firewire that I use for some audio stuff that's still going strong with just an SSD swap.
