Its over engineered in some ways and woefully under engineered in others. Any real effort in making it more performant or trying to extend it's life will just generate more additional ewaste than it will save by just reusing existing hardware.
The motherboard is modular and the compute part of this is replaceable, it's sort of the whole point.
The modules are mostly compatible between all of their products: MNT Reform, MNT Pocket Reform that are available now and the future MNT Reform Next (a more streamlined laptop) and the MNT Station (mini desktop pc).
Also there's a user story out there where a laptop is a mobile terminal and the actual processing power happens remotely in the cloud. With modern agentic workflows and how fast they're changing it makes sense to optimize for longevity on the client hardware.
