The problem as I see it is not crashes and leaks. It’s that basic features are barely functional and the UI is not very usable.

Stupid examples from recently:

- The iOS 27 Preview app’s search feature appears to be present while in markup mode but missing while not in markup mode (this is quite reproducible for me).

- Mobile Safari regularly gets into a state where the overlay showing the current website domain gets stuck obscuring an important part of the site.

- On MacOS if you accidentally switch desktops you cannot switch back until the animation from the first switch finishes.

- Spotlight is still hilariously bad.

- The MacOS Music app’s AirPlay controls are barely functional.

- If you have an excessive number of desktop apps open, finding the one you want is gratuitously difficult. Sure, the bottom dock widget is pretty, but that doesn’t make it efficient.

- While typing this message, multiple different glitchy UI elements have appeared and disappeared.

- On iOS, if the keyboard is showing and you don’t want it, tough luck.
