But I think that's just because I'm accustomed to having direct access to files and filesystems, and the extra later of abstraction (already necessary to visually translate a filesystem) just becomes bothersome.
E.g. I still need to cd and ls in a very primitive and visceral way, feel my way around the warren like a mole so to speak, even if I can just click/tap on a screen or C-x C-f.
Probably how the mind gets wired with basic text UIs like the DOS and Unix command lines, before you get to stuff like Midnight Commander.
Pretty weird, if you ask me, as that's more of a verbal and less than a visual way of interacting with the system, while I'm an otherwise visual person.
When traveling with an iPad (sometimes I take the Chromebook) I find using a SSH or Mosh client app with a remote server works very well. Your mileage may vary.
I never found a good solution, so I pack my iPad Mini and my Macbook. I just need stronger legs.
