Film grain is often beautiful and interesting. Digi noise is to be merely tolerated (by me). Yes! Film's artifacts are a part of it's character, in a good way. Maybe because it's what's been around and therefore I am used to it, but I like it!
And finally, an imaging system whose sensors are removable, replaceable, updateable, by the user, and diverse in character is a stroke of genius as far as I'm concerned.
