I know of one photographer who gave up on photography when Panatomic-X was discontinued. He just quit, in one single moment. Never heard from the guy again.
But, he had more problems than film choice on his mind, it seemed, so it was probably highly excessive behavior.
I've never tried Panatomic-X, but at the same time I try very hard not to be 'hung up' on a single type of film. Great pictures look good on any film, but that 'special' film does not improve your photographs much.
