I refuse to buy hardware when it comes out, and I only buy used hardware from private sellers on ebay. And only hardware that I know there's a possibility of me (read as: my clumsy hands) repairing it without having equipment worth 10k$. The reason I am doing this is because I had several Macbooks and Ultrabooks when they were cool and shiny, and all of them died within less than 2 years. So I kinda learned my lesson. This sadly limits the options to less than let's say 10 devices. For now I am still using my 10 years old T440p because it's the last generation laptop that can both run coreboot and is still repairable (and it survived all the Ultrabooks I mentioned before. WTF?). But it's too old for Vulkan because there is no Haswell support. It was the perfect laptop until around 2020 when Vulkan was rolled out. Can forget games that ran before that now, because of mesa dropping support for it. The framework will very likely be my next laptop if the current one dies, but only time will tell if the promise is worth the price. Fairphone 2/3 are kinda useless as an ideology if there are no replacement parts available 12 months after the phone came out...so yeah, I got also two broken Fairphones I cannot repair for the moment because the bottom module isn't available anywhere. I kinda refuse to buy a full phone just for spare parts because I can do that with literally every other cheap Chinese Android phone. With the T440p there's no working new mint condition batteries available and only used ones that have less than 60% capacity when you buy them, so I am currently trying to design a battery case that can use 18650 cells directly without soldering. Takes a lot of time to iterate, and very hard to print with a cheap 3d printer. I think I am way too stubborn for this world, given the amount of time I spend on fixing my old hardware.
