The new pinebook pro looks like a better product, but I don't own one so I can't really comment.
I also agree that MNT looks philosophically interesting, but it also looks highly opinionated to the point that it is a challenging sell even for the niche audiences of people who want an open source laptop and/or an ARM laptop.
(and there's also a bounty apparently! https://www.bountysource.com/issues/88375235-reverse-enginee...)
I'm surprised you don't like the keyboard though, I found it to be shockingly good. I often write on it instead of some of my other keyboards. I'll add the disclaimer though: I like apple scissor switch keyboards, and dislike mechanical keyboards. So that colors my opinion.
This is very much a laptop that has not allowed perfect to be the enemy of good, and I'm glad it exists. And I'm glad I got one!
