I had the same problem, couldn't find anything reasonably good for a reasonable price. My 11 year old MacBook pro was unusable with debian and all derivatives. As last option I tried Arch, and finally resurrected. It's usable again, and I will keep using it till the end

I'm not looking to replace mine right at this moment. Because currently, my 10 year old laptop is still running alright. But it is 10 years old. So I figured I would at least glance around and see what I could find. I did find one that looks pretty decent for 1.6 Monero, though. So I guess that's not too bad. I would still have to install Linux on it myself, but that's not particularly hard. It would just be nice if it came by default.
