I've run Linux as a daily driver recently Flatpak and Flathub still break all the time. Not to mention the last time I bumped my Nvidia drivers nothing decided to open anymore.

Any OS that requires even once going to the command line is unusable for 99% of the population (and for me I just shouldn't ever have to).

I hit this recently - nVidia issues with a Flatpak, I spent about half an hour on it, gave up, and just decided to try the app out on another laptop.
