Eric:
Slide projection has to do with the photography history, it is
a cult and it's a personal challenge for the photographer, you can't
use a computer to correct your errors, it's a way to your growth as
photographer; you think different when you know the image will be
projected and the slide is the final product. Slide projection still
offers a more detailed image than a digital projection, in spite of
the advantages you mentioned for the digital way (brightness has to do
with the screen features too), this issue was discussed here some time
ago.
Rollei, Kindermann, Reflecta and a few others still manufacture slide
projectors, it happens because there is a market for them, there are
people preferring analog slide projection.
