I ended up using my iPad Pro 2018 as a third screen (via Airplay) below my 4k monitor. My MBP sits on the left. It‘s an excellent setup running iTerm on the iPad screen, calendar or email on the MBP screen and editor / IDE on the 4k display. Other than that I use the iPad Pro for occasional couch surfing. iOS is just too limited to use the iPad Pro for pro use-cases. Would love to have macOS on the iPad though. Sometimes I connect the iPad to my MBP via Airplay and do some coding on it (using macOS with a full keyboard / mouse) in another room, away from my desk.
