Well,
the whole thing of whether digital or film is better, I expect you know, is rather absurd. I know you weren't actually pointing that direction in your post, but it sure seems a lot of people think that way. I still use a split. It amkes no sense to me if someone is paying for a couple hours to set up an architectural shot to shoot it on digital.
What the digital has done for me is pretty much replace 35mm. I still shoot medium and large format film and scan them. It is possible to get meaningful resolution on a good 120 film and lens up to about 3,000 dpi, which results in nearly a 200 MB file on a 6x9 shot. Plenty for any situation. You can't extract as much out of 4x5 due to thicker base and generally lower quality optics, but you have roughly 4 times the film area.
