In terms of quality from 35mm slides or negatives remember that
dedicated film scanners have optical resolutions of 2700 dpi whilst the
best flatbeds have only 600 dpi optical (despite exaggerated
interpolated figures). See Eg. the Nikon Coolscans at
http://www.klt.co.jp/nikon/EID/Film_Scanners/index.html
and my pages at:

The big advantage of digital cameras has to be their instantaneous
results if their lower quality is acceptable for the purpose (eg. screen
display only). I still feel that the effort and time of taking the
photographs justifies using 35mm (or better), archiving these and
scanning from them. When digital cameras reach the same definition as
film, RAM costs 10p a Mb and screens have 300 dpi resolution then this
will change perhaps.
