Film is relevant to me because it helps me think differently and work differently than I do with digital. It gets me away from the computer, it keeps me from chimping, keeps me focussed on the subject and the craft. The cameras are great for starting conversations too. When I hand somebody a Holga and ask them to take my picture they are generally truly amused.
My use of film is "about me" and "about how I interact with the world", it is no longer a technical argument for me and never really should have been.
