Maybe try to get repair parts on ebay? Don't have too much experience with plastic components braking down, but I understand the planned obsolescence frustration. Mostly around phones, in my case.

But yes, I hate all of this planned obsolescence. I have an ASUS C100P that reached end of life several years ago, so I need a new operating system. It was cheap and has a good aluminum chassis and good other hardware, but I need an up to date OS. I think maybe with enough effort Arch Linux ARM might be able to work, but would like a more polished OS.
