NeXTSTEP, OPENSTEP, Rhapsody, and Mac OS X are all the same OS as far as I'm
concerned.  I still laugh at the claims Apple ported "Mac OS X" to Intel. 
The initial versions shipped to Apple developers didn't run on PPC, they
ran on Intel CPU's.  Are we supposed to believe that Apple was foolish
enough to not develop Intel and PPC versions side by side as an insurance
policy?

The NeXTSTEP origins are still very visable under the hood of Mac OS X.
