Think this is more of a pipe-dream though, considering that 10 years is a long time for PC interfaces and internal interconnects. Swapping between different laptop manufacturers will be unlikely to happen, I feel.
Framework allowing for the whole mainboard to be replaced seems like a good halfway meeting point, and each case size being a constant chassis that hopefully will be supported for a long while.
Hope that other manufacturers follow suit, and at least have their own lines of upgradable laptops.
It's interesting to see how modern technology is built. I'm guessing FrameWork's factory is pretty immature compared to bigger companies like Dell, but even still they had a pretty nice setup. There's a good chance I might get their AMD laptop once it starts shipping. The price isn't actually bad at all. For a business laptop it seems right in line.
When my current laptop eventually dies, I'm gonna see what framework has before any other. This looks like something that I could upgrade & maintain for decades
