I would disagree with you on this KenJohn - there is plenty of opportunity to "fiddle around" with the Mac under the hood if you really want; it is Unix after all! You just need to be comfortable with the terminal. The power is there if you want it, need it & know how to control it(!) but as most people haven't got a clue about how to drive the 800-ton, 48-wheeled behemoth which is Unix, it's better that it remains safely hidden until such time that you may need it!

In my opinion, this is why the Mac is the best of both worlds for those of us who can "speak" Unix - fluffy, cuddly GUI when we're using the iLife suite of tools; hard-core command-line when we need to "get dirty" with the ability to install all manner of Unix packages! For example, all of my text processing is done by an installation of LaTeX and edited using TeXnicCenter; it produces beautiful, professional documents without the need for Pages, Office or even Neo/Open Office - steep learning curve, though
