I like simple and traditional, so I still use a Leica as well. I'm using 35mm less these days but when I do, it's almost always a Leica.
Another reason is that I can carry two bodies with four lenses and 20+ rolls of film and other stuff in one small shoulder bag. As I get old, older and older still, I'm paying for those many years of daily carrying a big bag of motorized Nikons. My neck, back and left shoulder hurt. They hurt less when I carry less.
