Hrrrm... What if someone made the same argument to Guido back in 1991, "This whole Python hobby is cool and all, but unless your time is worthless, use Perl"?  :)

Thanks to Savvas for the config! I've been meaning to try quad-buffered stereo in linux, now it's a bit easier. I looked at that Xorg config file, there really isn't anything that exotic in there, but I know how tricky it can be to find "that one" undocumented switch somewhere. However, for people used to Linux, it's nothing that weird.

Thank you for aggregating and posting that information.  Just so everyone
knows, it is possible to do this on a CRT/LCD-dual-headed Mac Pro with the
Quadro FX 4500 graphics card.  Having recently set this up for myself, I can
attest to the fact that "it just works" without mucking with config files.

However, the Mac price is signficantly higher because Apple only offers a
high-end stereographics solution -- nothing but the best, I guess.  Thus, in
bottom-line terms:

If you have more time than money, lean toward the Linux-based solution.

If your time converts to money, then weigh acquisition costs vs. management

If you have more money than time, then lean toward a Mac-based solution.
