I was told the following:

"The TFMs and VFs that come with TeX refer to those versions of the
fonts, that were de facto standardized as "PostScript Base fonts".
Adobe has applied a few changes in the meantime, so the fonts
you can purchase nowadays have different metrics.  Unfortunately,
they have still their old /FontName, so you cannot use  the new
version and the old one (or a clone of the old one) simultaneously.
Using the new fonts in TeX would, indeed, require to re-make all
TFMs and VFs."

I don't know if there is a noticeable effect, but the amount of time it  
took for me to recreate all the support files wasn't too large, so in  
my mind was worth it.  After all, why go through the trouble of using  
TeX if your output is sub-optimal?

I would strongly disagree with not downloading fonts for several  
reasons.

* Nothing is changed in the default case.  After all, the default latex  
font is computer modern and is it is *always* downloaded into every  
document you make with the default font.  That also goes for documents  
created using  utopia, cm-super and latin modern...  This only is an  
issue if you use mathptm, mathpazo...

*None of the printers I use have the standard PS fonts (including  
Brother and HP printers), and this is becoming more and more common.   
At least if you download the fonts into your document, it will print  
consistently on any printer and you don't have to have faith that the  
printer has the fonts in the first place.  Again, why take the time to  
use TeX if the output depends on which printer you use.

* I own the standard fonts.  Why not use them!  I know that my  
documents are consistent and use the standard fonts.  I don't know that  
the printer I am about to use has the standard fonts or some knock-off.
