And old/unsupported OSes like Mac OS X 10.5.8 and W2K SP4.
Hey, I have an 11yr-old Win2K-SP4 box! I have Flash 22.214.171.124 (last version to install on Win2K) on it but to be honest I don't browse on it much. Mostly a backup machine these days. That said it works fine although a bit slow. -- Don't feed trolls--it only makes them grow!
