I have schematics for every circuit and case part. I can (and have) use these to make whatever changes I want. If I run into trouble I have direct access to the engineer who designed them.
It uses standardized batteries I can get from many vendors for the foreseeable future.
If the screen breaks there are at least four different part numbers I can order to replace it.
I do not have to use a trackpad. The keyboard is mechanical and several layouts are available, some from third party designers.
The design of the laptop was a public affair in which I directly participated. I can include patches in firmware bug reports and they will be merged.
Instead of buying a new laptop every few years, I finally have one which has no secret sauce and I'm not locked into a vendor. Since I work in IT, I know how to take advantage of networking and distributed systems to leverage faster computers when I want to. In short, it's the computer I've always wanted.
I don't care that it's unfashionably thick, but others do, and I don't see any reason MNT shouldn't cater to them as well.
People can and will pay for a sustainable product made in a first-world country by workers earning a living wage. If you want a cheap Intel laptop, there are hundreds to choose from. The existence of a product which doesn't fit the norm doesn't make it "shit," it just makes it something you personally won't buy.
