Mac OS is POSIX compliant and has a terminal. That's pretty much where the comparison ends. Blah blah blah freedom blah blah. That aside, the Mac desktop doesn't really do it for me.

The best desktop, IMHO, is no desktop: tiling window managers give a pretty serious edge for any info-junky willing to climb the hill.
