Yes, but then why is there a problem?

I mean, my setup is the standard one on the Mac, the Latin Modern  
fonts are there at the appropriate place /usr/local/texlive/2007/ 
texmf-dist/fonts/opentype/ for use of OpenType fonts by TeX and  
friends, and for good measure they are also installed at the  
appropriate place /Library/Fonts/ for use of OpenType fonts by GUI OS  
X applications.

Then, if Latin Modern is indeed fontspec's default choice of fonts  
when none are specified by the user -- and the [cm-default] option  
isn't used --, why aren't fontspec and/or xdv2pdf set up to find them  
by default? I have no idea who's culprit here, but isn't a default  
setting supposed to work out-of-the-box? And to me the following:

\documentclass{book}
\usepackage{fontspec}
\begin{document}
Anne{}-Marie Anne-Marie
\end{document}

seems as close to use of default settings only as could be.
