Joining the chorus of the "I'm not sure it's worth it..." brigade here. About one-third of the time, the flight attendants in F aren't even aware transcon first is a different service rom shourthaul F. Once I asked about the salad course (after they skipped it), and he said, "Oh, so THAT'S why I have so many salads left over up here." Super friendly - no complaints there - just unaware Transcon F was different from the regular shorthaul F service.
Celebrity sightings, yes, very true point there, if you're into star gazing. My experience has been the first two flights Monday mornings from LA to JFK have the highest chances of seeing someone famous.
Good luck with the upgrade, but my advice would be not to pay a lot for it - you might be disappointed.
