There may be things users have grown to 'tolerate' that were accustomed to using only a desktop environment that may surprise those who might've managed possibly faster workflows on something like a tablet.
What a silly reason to not use something.
I always figured that whole branch of design came out of dealing with mobile limitations, with some amount of side benefit from more screen space to do useless but flashy things to make the boss/client happy.
Why would you ever go that route for a general purpose desktop?
Growth requires change and if you don't have a billion dollars up front you do this iteratively in small pieces by necessity.
I'm OK with a global menu bar, or app-window menu bar, but hiding everything behind a stupid hamburger thing on a desktop computer?
Weird choice IMO. I'm just living with it, though, since I don't really want to fuck around with my system itself.
Ubuntu Unity did not - it was great for classic desktop usage with Mac-like (most importantly, not a mediocre attempt to mimic but even better than the original in some aspects) UX + advanced supports for keyboard lovers + keeping the mobile in mind.
IMHO late years Unity was the best Linux UI yet. If only they would add Pop_OS!-like tiling + some more little Mac goodies only experienced Mac users know it would be perfect. And I absolutely can not say the same about GNOME3 although I actually want a GNOME3 tablet.
