Digital + Film

Wouldn't it be really neat (if really expensive) to combine film and digital into one camera? You'd have the best of both worlds immediately available at your fingertips. My favorite application for this: practicing in digital, then flipping a switch capture the moment with the already-confirmed-the-looks-good settings on film. I love film and I love developing it myself, but it's frustrating to spend so much on it + developing and then discovering that it's just a bit off from what you were going for.
