I disagree with the "OT" designation of this thread. Many people use
pdftex to prepare documents for a very broad audience (including documents
that will be archived and should be useful a few centuries from now). It
is critical to pdftex users that high quality viewers are widely available
now and "forever".

Adobe gets no direct revenue from sales of Acrobat on linux, so I assume
there are enough i386 linux machines to justify supporting Reader on i386
linux as a selling point for Acrobat over Win32-centric document

What are the examples of X11 apps that have been ported to Win32 or vice
I suspect it would take a huge effort to port xpdf to Win32 and get decent
performance with win32 look and feel. Adobe Reader usually works well
even on low-end Win32 hardware, but is not tolerant of buggy video and
printer drivers, suggesting that it exercises parts of the Win32 graphics
API that aren't used by MS itself. OpenOffice.org and Mozilla are
probably more relevant models for cross-platform GUI development, but
I don't know if they work on low-end win32 hardware.
