Mac to Dell/Ubuntu here and completely agree. I can understand if you need some media creation applications sticking with Mac (although I'd switch to Win10), but as a fellow developer it has been awesome. I mean I'm completely shocked how I don't even remotely miss anything from Mac. Well, ok, not quite true - Macs have a slightly smoother UI which I like and a bit better fonts, and I miss 1 or 2 trackpad gestures. But everything else is equal on Ubuntu or better. I ran into 2-3 problems that needed some non-trivial linux admin, so I'm not advocating it for non-tech person usage.

The only irritation about the experience is when you switch windows and touch the touchpad, it forces a quick scroll down the page. It used to be maddening, but I found one "fix" that made it happen less frequently.

Otherwise, it's by far my favorite dev environment I've had in my 30+ year career! Well, except for maybe my first job using a Wang terminal, if only because I enjoyed telling coworkers I needed to get back to my Wang. Lots of Wang jokes.
