This is the first time in my life I've seen a laptop like this. It's called Kubuntu Focus Zr GEN 1 and Zr Gen 2.
I find it curious that most brands follow Apple's path of soldering everything to the motherboard without the possibility of upgrades. Meanwhile, smaller brands are going in the opposite direction. I believe modular laptops are the right path; if they take away the modularity of laptops, our traditional desktop PCs would be next.
