I don't care how big or how great digital sensors become. For me, they will always be cold and clinical and create soulless, grainless captures. That doesn't interest me in the slightest. I could've upgraded to a 40D or 5D from my 20D but I have chosen to put my money into analog tech, namely Leica M and M-mount lenses. In retrospect, I should've just hung onto my 1D and I would've been just fine. I have definitely entertained the idea of a FF digital body but again, the pull of film is much stronger for me and I am invested in it for the long run. I'll continue to try to do my part to support the film industry.
This also reminds me of the mechanical watch niche, particularly in regards to mawz's comparison of disposable cameras and cell phone cameras. When I tell people I still enjoy wearing a mechanical watch (or any watch for that matter) I often get asked why in the world I would bother with it if I already have a cell phone. I have an atomic clock app for my phone but much like film photography for me, a mechanical watch has a soul to it. There is a chaos/error factor that I think mirrors the human experience that is much more desirable to me than the sickening ocean of perfection and convenience of digital technology.
