Recent versions (0.90 and later) are doing surprisingly well.  Compile
it with Type-1 font support and it looks quite good.  Doesn't support
Javascript (as Acrobat 4 does), but other than that it's nice, and I use
it a lot because it's lighter than acroread on my Intel (and because my
LinuxPPC system doesn't have an acroread available).  The interface is
clunky but it's quite useable.  We actually used it for our tax forms
from the US Internal Revenue Service in 1999, and it was good enough for
them.  *smiles*

Of course, Ghostscript and viewers that use gs are quite good these
days, too, although not quite up to the level of the PDF-specific
viewers.  But gv or GhostView would be an option as well, and of course
the viewer end is GPL'd.
