I determined a few years back that I likely would never expose another frame of color film. It was just a personal choice. Black and White, as well as film, are choices made subjectively (for me) and not based on what is "better".
I can't find the quote or the reference right now, but a little while back the photographer Carl Weese was quoted as saying something to the effect that black and white was perfected with film, but color was now coming of age in digital. So, I know I'm not the only one.
David, I am in the same boat. I have not wound on color film since 2004. I do not see that changing in the future either. I have come to love and appreciate black and white so much that I think any color photography I did would be lackluster at best. I'd be shooting color film while trying to photograph black and white subject matter.
