On the point that an elegant user interface isn't always important, I'll point out that there are even a lot of people around who disdain a GUI, and look askance at anyone who can't do everything with command-lines--here's a random quote that I found when I googled "I hate GUI's":

" ...ultimately what's wrong with a GUI: A GUI will only let you do what the GUI's programmer envisioned you needing to do, and programmers frequently have no idea what administrators need.

That's why command-lines are better: They're infinitely more flexible. I would even go so far as to say any command-line, even Cmd.exe, is better than a GUI when it comes to hardcore administration."

To each his own... but I still love my Mac.
