A lot of why I use film has already been summed up in this thread... namely, I just prefer it. No matter how good digital gets, it will never look like film. Be it the grain, tonality, whatever. That's not saying one's superior, they're just different, and I prefer film personally. I love the fact that a film negative is an actual physical piece of something that happened or was seen. The actual light from that scene affected the silver halide, and the negative (or slide) captured that moment in time in a tangible form. I also prefer getting all excited with a roll of film to come home and develop it rather than instant feedback on the 2.5" screen on the back of my digital. I don't like instant feedback. While there have been a few times that I got excited about a roll of film only to ruin it like an idiot, I still prefer that. Film also limits your exposures. Rather than just snapping away like an idiot, I think and compose with film, and unsurprisingly this shows up in my final result. I can go shoot all day with my digital, hundreds of shots, and come home with 20-30 good ones, whereas on a 35mm 36 exp roll I come home with 20+ quality shots pretty regularly and most of the other exposures were simply duplicates.
