Us Germans like to think in hierarchies, and these are best reflected
in the kind of computer one gets ;-) Thus, the poor students who work
a little during their terms don't have more than 8 bits, and even
several PhDs and postdocs don't have it. The problem with these Sun
workstations is that they are so robust, so there is no need to
replace them ;-)

Don't take this so seriously, but be warned that whoever is going to
cease support of 8 bit displays will be missiled with emails or other


PS: However, I think you are right in that RSI could make a move
toward adopting 24 bit displays as the current standard and only
allowing for 8 bit as a secondary option. I haven't thought about it
too much, but perhaps they could then come up with a better and more
user-friendly color model (forget about the tables, have at least 16
Million indices available, store more than one colortable, so each
application running concurrently can have its own and update colors
smartly, etc.)
