The other advantage of using jigdo is that it spreads the downloads
out across more mirrors. Not many of our mirror sites have the disk
and bandwidth to keep *multiple* copies of Debian (normal archive plus
the same files within CD images and within DVD images). Using jigdo to
get most of your data from a local mirror should generally be faster
than grabbing full ISOs from a central site, and it's nicer to the
people who volunteer their bandwidth to host those central sites. And
that goes double immediately after a major release... :-)
