Recent iphone models have “easily” removable back glass, and it’s actually the main entrypoint for replacing the battery, lowering costs due lower risk of a broken screen (see new google pixels with screens that almost always break on removal)
After this, apple also lowered the cost of most repairs, including on models that don’t get the new replaceable back. the non applecare cost for a battery replacement ranges from 80-100 dollars roughly. which is comparable to the cost of a replacement with even a generic battery from a 3rd party shop.
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
