Well, because PiNG is lossless, it doesn't compress nearly so well as 
JPEG.  As for general utility, allows for putting info tags in files, 
keeps resolution information, supports low and high color depths fairly 
well (including 48-bit color).  Really its niche is different from 
JPEG.  More like the areas covered by TIFF and GIF combined except that 
it doesn't support animation (for that they have MiNG).  In its early 
days, its biggest problem was that IE didn't support it.  Now that 
problem is gone.
