My Inspiron 5505 trackpad stopped working and Dell sent me a replacement. That didn't fix it and they determined it needed a motherboard. The replacement motherboard had some serious issues or didn't work at all (I can't remember, that was last year). They sent me a refurb 5515 in its place, and now it has locked up several times and has some weird ghosting/artifact stuff going on with the display.
Unfortunately, I don't know of any good PC alternative to Dell.
frame.work also gets mentioned here from time-to-time as they support Linux [1], however reviews of the product itself are mixed, so this is not an endorsement, just an observation. I would read hn history and frame.work forum history before buying one for my use.

I just ordered a Macbook.
