I also have an x200s that I got new in 2009. I've replaced the keyboard, battery (multiple times), palm rest, upper shell, and probably a few other things I'm forgetting about. I haven't put new parts on it for a few years, but as recent as ~2020 they were very easy to get and affordable. My little x200s is a dedicated HaikuOS machine now and I hope it keeps running for another two decades!
