This might be a dumb question, but for a dedicated Linux computer why would Starlabs choose Intel or AMD over an ARM design?

For a Windows computer, x64 makes sense because backwards compatibility is a big deal. But a Linux machine doesn't have the same problem, at least not to the same degree. Couldn't an ARM-based design be used to make a Linux laptop with Apple-like performance per watt?

They’re still going to be some point somewhere where you can find the amd64 version of a binary and not the ARM version.

I agree with you that it would be more rare than trying to live in Windows ARM world, but I’m not sure it’s entirely a lossless experience yet for your personal computer.
