Yup. Shoot color and B&W, everything from 645 medium format to 4x5 LF. Hasselblads, Rolleiflexes, Mamiyas, Pentaxes, Kievs, and a Norita :-)
I don't know if shooting film has, specifically, made me a better "digital" photographer.. I'd tend to think so, but basically, any kind of shooting should make you a better photographer in general. I know for a fact that I've become a better "film" photographer (very different approach to digital), but my main reason for shooting film is to shoot larger formats. If somebody gave me a full size digital sensor for all the formats I have (645, 6x6, 6x7, 6x9, and 4x5), I'd probably quit film. For better or for worse, that's not going to hapeen for a loooooooong time
