My magicbook came with deepin linux installed, but unfortunately they're based off debian stable, which meant that most of the packages were severely outdated and unusable for me as a dev environment.

The deepin desktop environment itself was pretty, but janky. The settings thing (on the right side of the screen) is difficult and unintuitive to navigate, and scrolling was still buggy when I used it in December (it will randomly skip sections or just get stuck when you scroll). The other apps felt similarly unpolished, like they'd put all their energy into the look rather than the boring stability side of things. In a few years it might be a nice DE, but it has a long way to go.

I've tried all of the major desktops over the past year in anticipation of 20.04, but I think I'll be moving to KDE once it comes out. It seems to have the most seamless integration of them all, and still allows me to control things. I just hope the performance is good.
