I've never been a super-hardcore simmer (although I do appreciate those sims) and yet I'm a cockpit-only flyer. This goes all the way back to Microprose's own Stealth Fighter where you better be keeping your head down in those MFDs and watching the indicator bars and lights. External screens do nothing for me, never have. But I don't see them going back to more modern aircraft anyway, with proper pit and single-player campaign.

The rusty wire that holds the cork that keeps the anger in
Gives way and suddenly it’s day again
The sun is in the east
Even though the day is done
Two suns in the sunset, hmph
Could be the human race is run
