I got it as a Windows machine and never ran anything else on it. Technically it was broadly fine. The specs were OK, it was reasonably repairable, I had a hi-dpi screen, the case was solid.
But the keyboard felt really dead, the wrist rest was smeary, the screen had a grainy impression, the machine was slower than its specs would suggest, and the 16:9 ratio and thicker/heavier than expected construction meant there wasn't much to be gained from the narrow bezels on the screen.
I replaced it with a high-spec MS Surface Laptop, which is a risky gambit because the Surface is effectively completely unrepairable. But it has a better keyboard, screen (3:2 ratio), and touchpad, it's faster, and the wrist rest has a nice carpet on it. It's a pleasure to use so far, in contrast to the Dell.
It's funny how much of this still comes down to personal ergonomic factors.
