I recently got a last gen HP Omnibook ultra flip. Macbook level build quality but with a flip touchscreen, pen and oled screen. Really happy with it and everything works in fedora.

As others have said harmony is setup exactly the same as android, open source OS on which a closed source customized flavor is built. It’s exactly as bad or not bad as android is in this regard. The flavor being in control of a Chinese corporation instead of an American one is another issue.
