Two points to consider:

      * PostScript is the standard output format in the natural sciences
        and mathematics community. (Probably due to the prominence of
        LaTeX and dvips.) Also, since it's understood by many
        (semi-)professional printers it is often used for production of
        papers and preprints or as an intermediate format. On the other
        hand the only applications that would fit into this category are
        probably word processors, so general PostScript support is not
        necessarily needed.
      * PDF and PostScript have a slightly different application, in my
        opinion. PDF is used for "web publishing", i.e. stuff that's to
        be read online, but can also be printed out. It has lots of
        features that don't make sense on paper (links or automatic
        table of contents, for example). PS on the other hand is the
        lingua franca for communication with printers (the hardware
        kind). If you've got something as PS on Linux you can print it,
        transform it, do all kinds of silly stuff that falls into the
        "print preparation" category. It's a format very well suited for
        a (printer independent) "Print to file" option.
