Unix or Unix-like it is fine by me. After 14 years of Windows, 10 years of Solaris, and 8 years of Linux staring back at my face; it's a heck of an improvement for a desktop OS. In fact, OS X 10.2 was good enough for me to go out and purchase an Apple computer for the 1st time and get me banging away on it.
Apple is moving away from the NetInfo idea according to the rumor mill. For a 2.0 release on and OS, they have done a tremendous job!
I do not mind typing 'sudo su -' to get to a # prompt.
Thanks to Richard Stallman and the Free Software Foundation. Without them, OS X, Linux and lots more would never have happened.
