There is one other point that has not been brought up here. I like to call it the WOW factor. There is nothing like seeing those big negatives for the first time hanging after they are processed.
I know some people make beautiful images with the digitally output negatives. But I don't think I could give up that WOW feeling just for the ease of use in the field. When you see the negatives for the first time and make prints from them, it makes all the struggle in the field worth it.
