I use all different types of film cameras from 35mm up to 8x10 and am currently looking at a Canon S45 (smaller version of G-3) for some site documentation work that will go into a published report instead of film/scan routine. For Web work or incorporating photos into printed reports digital is a far better solution for those photo uses. At the higher end, medium and large format digital backs are the way to go for catalog/studio work.
But, if you're expecting to duplicate film performance in an enlarged photo with a digital camera - stick with film. New Kodak camera will be out in February with a 24x36mm sensor and 13 megapixels for about $5k based on the Nikon N80 body (special version).
***"I can't imagine it's very good as a 35 mm negative is very small***"
11,000 ppi Tango drum scan of 35mm frame and you can do 30x40 inch enlargement on a LightJet. No grain, totally sharp from edge-to-edge. Again, depends on YOUR final output requirement.
