When you consider the advanced film SLR and DSLR "experience" is similar, the answer isn't hard to suss out. You shoot a high tech AF film SLR in the same kinds of situations you'd use a DSLR, but shoot when you feel specifically like shooting film.

A good DSLR is a very fine piece of kit and my D300 is generally my first choice for things like event coverage, but it's not a total replacement for film. There's times when the F100, with the film options, is what I want even for chasing action.
