Hm, maybe that part is more polished, but I don't use it. My pain points are very basic stuff, quickly opening a file explorer, finding files, copy paste, navigating folders. It all improved, but still feels awkward and is way slower (takes more clicks/key presses) than in linux or windows.
I have never had any problem with any of those things on any OS I have used. Pin the files app to your taskbar, boom, easy access to files and folders. Hit the circle key and type in the launcher box to search. Copy paste is...identical other than Ctrl vs cmd?
ChromeOS is fine. I wish they hadn't given up on Steam and models with dgpus, but I prefer playing games on a Switch these days anyway.
