jAAck,
Having the window shade cracked, even "a bit", illuminates the entire cabin-- I know from personal experience. After doing this myself on one of my first long-haul F class flights and being surprised at the impact on the cabin (and immediately noticing a couple of passengers starting to wake up because of the lighting). I, too, like to occasionally look outside and see natural light-- when I feel the urge I walk back to the galley to avoid inconveniencing the other pax.
The equivalent examples that you cite have rarely or never happened on the 40+ long-haul F class flights I've experienced on CX, QF, BA, SQ or OZ in the last two years:
incessant talkers who never sleep (once, for half the flight);
FAs gabbing in the galleys (never, F class galleys are frequently placarded to remind the FAs to keep their voices low);
crying babies (never);
toddlers roaming the cabin (never);
occasional knock in the shoulder or leg by a passing cart (never).
There is a significant difference in the inflight experience between J and F class on these long-haul services and that's why people typically pay a premium of several thousand $ over J for their tickets.
Maybe this is yet another reason to steer clear of AA int'l F class flights.
