I have a forty-year-old Leitz Pradovit projector that I talked my folks into buying back then.
I have never had a Leica camera (so I voted "No").
I have used compact, fixed-lens RFs for travel, mainly because of their small size.
Otherwise, I use SLRs for 35mm and TLRs for medium format.
Still shooting film: Medium Format with assorted TLRs; 35mm with manual-focus Minolta SLRs and a Canonet.
