I would like to ask why even fight the battle?

Philosophically I am with you, e-waste and consumerism are bad, but pragmatically it is not worth punishing yourself from a dollars and cents standpoint.

You can jump on Amazon and buy a mini PC in the $300 range that’s got an 8 core 16 thread AMD 6800H CPU, 16GB RAM, 500GB SSD, basically a well above-average machine, with upgradable RAM and storage. $240 if you buy it on AliExpress.

You can grab a MacBook Air M2 for around $500.

Why suffer with slow hardware? Assuming that using a computer is at least somewhat important to your workflow.
