Just a few observations:

1) PDF is designed to be used with a dedicated browser application (e.g.,
   acroread).  Thus, embedding interactive elements into the PDF via Javascript
   makes sense, when used in this context,

2) Display PDF isn't necessary a full implementation of PDF, and in fact, is
   quite likely based on a proper subset of a more elderly version of the
   specification,

and finally,

3) Javascript's I/O model isn't as flexible as a general purpose
   user-interface coded at the OS API level.  Using Javascript to manage the
   user interface in MacOS X (or other system which uses PDF) would be
   insane.
