chromebooks are often well built with good keyboards at prices monumentally lower than comporable laptops, whilst being powerful enough to run linux well

you can quite easily get linux on almost all chromebooks, even arm ones (mrchromebox and postmarketos are references to look into for that) (postmarketos for arm stuff)

I have an hp chromebook g7 that I paid less than 20 dollars for, which has a good keyboard and is performant enough for firefox and typing on swaywm. it’s worth so little and is so light that it can just live in my backpack without worry. it’s also able to be charged from a normal usb c phone charger, supports usb c display output, and has a low power celeron that absolutely sips power

you can get much nicer chromebooks for cheap too if you’re into that, including some with unibody aluminum chassis and high resolution ips displays, all at prices less than even bottom barrel pc laptops

not to be a downer but you could very likely buy a higher performing laptop than even the top framework laptop for less money than even a minimal build
