Let me put down my reasons more clearly for shooting jpg, not because I want others to do the same, but simply to see if I'm not deceiving myself.
I imagine myself, as a photographer during the film era and I'm shooting Kodachrome 64. When I go out, I know the limits of the film, and so on and I meter carefully and shoot. I send the film its developed and sent back to me. i go through the slides, throw away the one's that I don't like, mostly due to bad exposure and and keep the ones where I succeeded.
Now, why I should not follow this simple and elegant system with digital?
I go out my digital camera, shoot jpg and expose carefully. During editing I pick the ones where I succeeded and delete/archive the rest... Where as I used to go out, meter casually and then during editing decide on which files to process and each files took so much time and next thing, I was too afraid to even touch the backlog.
I'm shooting slide film, with a digital camera.
