PDFs do have hyperlinks, so that in itself isn't an argument for keeping
the dead-tree-friendly approach.  However, I've noticed some variation
among tools in whether a PDF hyperlink is visibly distinct, or whether
you have to mouse over it to find out that it would take you somewhere.
Not sure if that's enough of a usability fail to argue for keeping the
old way.
