In my case it will be driven by VNC either from a tablet or another PC located away from the mount.
When truly "in the field" you would need a small screen keyboard and mouse unless an ad hoc wifi setup still allowed VNC access, not something required in my application at home. The benefit of the NUC or Rpi compared to a laptop would be the ability to run it off 12VDC supply, plus having a small and cheap box out in the dew instead of an expensive laptop.
I can see my eventual obs having this on the mount wifi'd back to a desktop in a warm room, saves hassles of long cables, active USB extenders etc.
