Hi Jason--

I can't speak for everybody.  

I will say that in the astronomy profession there are a lot of tools
that run only on 8-bit displays.  Part of that is just legacy, and
support for 24-bit is improving.  On the other hand, there are a lot
of times where it's really nice to have a color table to manipulate,
to do things like interactive intensity scaling, or just to futz
around with the color scheme.

Lastly, on a lot of systems I've seen, the 24-bit graphics are quite a
bit slower, and of course they use more memory.  In "economy"
situations, 8-bit would be the way to go.
