Who shoot on auto film cameras?....Well, I like to "pick up my camera and go", without worrying whether the battery is charged up or not. Whilst I usually prefer all mechanical bodies, the batteries in my Nikon F90x last at least 6 months or so.
When I was working professionally, the digi stuff was a nightmare of unreliability, with battery drain (even when not in use) the main problem. Even without drain, digi cameras eat up battery power like no film camera does. You could never be sure when your digi would suddenly run out of power.
Also, whether it's a case of only 36 shots on a roll, I always work more slowly and carefully with film, usually resulting in better pictures.
