It seems as though digital is at the point of film in terms of quality...I have dreaded this for a long time.
It is always a good time to stock up on film!

Film has not yet been surpassed as a quality medium.
For instance, a typical digital output is a JPEG and current "high standard" is 10Mega-pixel.
WHile film is losing mass appeal in a lot of cases, there is a lot of untrue hype as well.
So, here is a quick back of the envalope calculation that can be skimmed without :
Digital -- 10Mpix -- 8 bits per RGB color (and per pixel) -- 10Mb of information (without interpolation)
The following have 3 colors per pixel, so the # of bits multiplied by 3)
FILM
8mm "Minox" film -- 3.3Mpix -- ~24 bits/color -- 29.7Mb of information
35mm film -- 22Mpix -- ~24 bits per color (72bits per 'pixel')-- 198Mb of information
Medium format 6x4.5 -- ~60Mpix -- ~24 bits per color -- 540Mb of info
Medium format 6x6 -- ~80Mpix -- ~24 bits per color -- 720Mb of info
Medium format 6x7 -- ~100Mpix -- ~24 bits per color -- 900Mb of info
Large format 4" x 5" -- ~328Mpix -- ~24 bits/color -- 2952Mb of info
Large format 5" x 7" -- ~574Mpix -- ~24 bits/color -- 5166Mb of info
Large format 8" x 10" -- 1312Mpix -- ~24bits/color -- 11808Mb of info
So, for resolution, 8mm Minox film is inferior.
The rest has more resolution assuming it is fine grained film.
Grain is the big bugbear and prevents large magnification of film - and because of the aggressive noise reduciton, it will allow very large magnifications before it looks "bad." I don't think anyone has published anything about applying the same routines to film and the results?
Also a lot of digital photographs use high amounts of "sharpening" which people think looks good now, but looks terrible under scrutingy. This will "boost" the apparent resolution by emphasizing edges, but in many cases distors details int he pictures.
Anyway, this is kind of long, but this is kind of a hot button with me - and I am not sure why as I have both digital and film cameras - though I do prefer film due to the better shading and subtlety of coloration and lack of artifacts.
