I agree, it should not be there for most users. Maybe the final release of OS X will not even come with the Terminal program. This would ensure that the new users, even the mac veterans would not need to use any UNIX ever ... if they don't want to.
however, I use command line daily - even prefer it sometimes, to the gui. I think it is great that it is there for those us who know how to use it, and WANT to use it.
Example: maybe php will be a push-button install that can be done from the gui one day (I think it is pretty much there with Xtools from tenon). Until then, here is something I would have never dreamed of trying to install on my old mac OS, and it is now running on my powerbook with X beta - this is great! I installed it from the command line, and learned something in the process.
I think for the mac user with no unix experience, the final version of OS X will be what it is intended to be: a more stable, modern operating system. For the UNIX/Mac users, it will be a dream come true: the macintosh interface on top of our beloved unix - we now have the option to use gui or not, to use our machine for games, word processing and graphics work, or as a full featured web-server.
just some thoughts...
