I also got a pinebook pro and I managed to use it a sum total of 12 times (and only on flat surfaces with the power plugged in because otherwise the screen would flicker like a strobe light) before the screen completely gave up and now it's an expensive paperweight.
Still I will keep buying these things.. eventually someone will figure out how to make reliable laptops that align with the ethos of free software. I've researched system76, puri.sm and also lately the way too expensive MNT reform, but really the only laptop people seem to be happy with is thinkpad x220 / x230 which came out 12 years ago.... This makes me sad.
I would pay a lot for a super sturdy laptop which works (and aligns with the free software ethos).
I've run Fedora and a custom Debian setup in the past (and currently am using Void Linux). Things mostly work with no real issues.
I think perhaps the mistake is paying premium with new and shiny things that haven't stood the test of time is the problem here? If you buy cheap (something that is a known quantity also), you're less likely to feel the b urn of walking away from the shiny / expensive new thing, right?
Note: I also have the X230 (bought off craigslist for ~$100, 2 years ago) and have given that to my dad who has used it happily for years now.
