Dell and Lenovo generally do a pretty good job, and those machines sell well, but I think the quality is still below what, say, Apple can deliver. Judging by the push to get Linux to run on Apple hardware, I'd say Linux enthusiasts are not only willing to pay a premium for a quality product, but willing to invest time and effort getting it to run well in a hostile and closed ecosystem.

So I think there's a big market opportunity for someone to deliver Apple quality hardware, that integrates well with open source software. Framework is probably at the frontlines in this regard.
