The 4th gen butterfly keyboards work fine. I have two (personal MacBook Air and work MacBook Pro) and have had no reliability issues whatsoever over the past year. I also love the feel of the keyboards.

I don't have any personal experience with the fan noise issue, but I'd advise trying to get some first-hand data on it.

Whatever laptop you switch to is also going to have its issues and imperfections. There just isn't a contingent of people loudly complaining about them all over the internet. So for example, here is a comment elsewhere in this thread about using Linux on a thinkpad:

>If you feel that you don't need a 4k resolution screen, then I would recommend getting one with a regular HD or a Quad HD screen instead. Scaling is still not optimal on X11, and it seems to take at least some toll on the CPU as well (which will also result in your fans spinning up from time to time).
