The argument I've seen is that selecting font sizes isn't a linear operation 
(i.e. proportional to dpi), but an angular one (i.e. depends on the size of 
the screen and the distance to the screen).  So for example laptop users sit 
closer to the screen and don't want fonts to be so much bigger as implied by 
the dpi difference.  Another one is that DPI is kind of fuzzy anyway, for 
example for projectors.

I think a good compromize for an Emacs that uses Xft, is just to check if 
Xft.dpi is in the Xdefaults, and if it is, just use it.  Which is what 
Handa-san suggested.
