idk. i don't think there's a good story if you're primarily interested in full-cycle e-waste minimization and avoidance. the mac hardware is good and is designed to live on timescales like that (probably because they are primarily aimed at building a good consumer brand) but it's also impossible to upgrade so there is some built-in planned obsolescence in that regard. (although it can be sold and replaced with other higher spec used gear).

the thinkpad and dell stuff is more upgradable, but is largely aimed at business markets where they plan on refreshing every 3-4 years.

i think maybe you get the most longevity (and possible warranty) out of thinkpad, but sadly none of this stuff is really designed to last that long.

e-waste sucks. unfortunately, our current dominant system of production doesn't really reward design for longevity. refreshing technology on the regular makes for a pleasant consumer experience, i wish it were less environmentally damaging.

framework has an angle on this, but i think in practice they're somewhat equivalent to thinkpads in terms of extendability. i also wonder how much you actually save when you start replacing everything over the long run.
