I was thinking about this recently, for the myriad failings of mobile systems (non-free hardware and software, walled gardens, software design geared toward rent-seeking, etc.) they sure have great usability. Apps are rarely an incomprehensible mess when you first install them. Settings menus can get messy but it’s often easy enough to find what you need and quick settings are never more than a swipe away.

Desktop systems have tons of unaddressed pain points that have no reason to exist.
