Leader keys + Evil mode make the keybindings pretty much non-issue on mobile. Emacs also has native Android port now, I've found it work quite well. There are apps like orgro[0] that make dealing with org files a pleasure on mobile.
That being said, it is not perfect. My ultimate (and imperfect) solution was to acquire a GPD Micro[1]. Now that thing makes up for all shortcomings of mobile devices, not just Emacs :)
Same thing as my main laptop: NixOS + Plasma desktop.
I barely see the desktop TBH. It is there just so I have convenient control of peripherals. 99% of my time is in Web browser or Emacsclient or Terminal. On GPD I use the browser even less, because its purpose is to be a lightweight mobile terminal. Graphical Emacs is just superset of terminal one, so it is preferred is all.
