I'm just writing to describe my recent experience with KDE Plasma through KDE Neon. I heard your predictions episode and all of the great things KDE is bringing and thought I'd give it a try. I had a 2018 15" HP Envy laptop that never fully worked when I installed Ubuntu proper, Ubuntu MATE, Xubuntu, and lastly Deepin. It always had some glitches that I would have to put up with when running off of those distributions. KDE Neon worked great, and I was surprised at how beautiful it looks stock. It was a bit rough trying to install the distro in high dpi (good thing I wasn't new to distro hopping), but once installed, I was pleasantly surprised and can see why so many people champion Plasma as their desktop of choice.
