the classic example is link breaking. if you have a long bit of text
to make into a link, pdftex can break it into multiple links, amd
linebreak nicely. dvi-based methods just crawl away in despair and make
a long unbroken link. People do claim they could break links at the dvi
level, but I don't think anyone has actually done it
