The ability to use xdvipdfmx is quite convenient on the Mac. What  
I've noticed:

- It seems to produce much smaller PDF files that xdv2pdf (like 100  
KB with xdvipdfmx and 500 KB with xdv2pdf, for the same input file).

- The impression of documents produced by xdvipdfmx seems to take  
longer. (Here on an HP LaserJet P3500, the printer spends a bit of  
time processing each page individually before printing it.)

- Thanks to xdvipdfmx, it's possible to use the hyperlinking  
facilities of eplain (which only offers drivers for hypertex, pdftex  
and dvipdfm). This week I was working on a document for which I  
wanted to use plain TeX for a change (instead of LaTeX that is), but  
I needed color and hyperlinks (I would have liked bookmarks as well,  
but that doesn't seem possible). This wasn't too difficult to get  
with eplain and xdvipdfmx, using input like:

\input eplain
\input ifxetex.sty
\ifxetex
   \beginpackages
     \usepackage[xetex]{color}
   \endpackages
   \enablehyperlinks[dvipdfm]
\else
   \ifpdf
     \beginpackages
       \usepackage[pdftex]{color}
     \endpackages
     \enablehyperlinks[pdftex]
   \else
     \beginpackages
       \usepackage[dvips]{color}
     \endpackages
     \enablehyperlinks[hypertex]
   \fi
\fi
\definecolor{legiblue}{cmyk}{1.00,0.45,0.00,0.18}
\ifxetex
   \hlopts{bwidth=0,colormodel=,color=legiblue}
\else
   \ifpdf
     \hlopts{bwidth=0,colormodel=,color=legiblue}
   \else
     \hlopts{colormodel=,color=legiblue}
   \fi
\fi
\def\doi#1{\href{http://dx.doi.org/#1}{DOI:#1}.}
\ifxetex
   \font\tenrm="ChaparralPro-Regular:mapping=tex-text"
   \font\tenbf="ChaparralPro-Semibold:mapping=tex-text"
   \font\tenit="ChaparralPro-Italic:mapping=tex-text"
   \rm
\fi

Regarding the ChaparralPro font that this example uses: I recently  
noticed its availability in /Library/Application Support/Adobe/ 
Fonts/, and found it quite nice. I'm not sure which Adobe app it's  
installed with; I have Reader, Acrobat Pro and Illustrator.

However, the /B font "modifier" of XeTeX doesn't work fully for this  
font: the font comes in 4 weights Light, Regular, Semibold and Bold;  
Light/B switches to Semibold, as I suppose is intended, but Regular/B  
switches also to Semibold, not Bold. Arguably, the Bold weight is a  
bit heavy to my untrained eyes. But isn't Regular/B supposed to yield  
Bold?

Nothing in the above is important in any way, I was just wondering.
