I use Distiller.  It makes it really easy to ensure a compliant
document that others SHOULD be able to open and use.

Ever open any PDFs that contain script?  Multimedia files  (audio and video)?
Page transitions?  Embedded payloads?  3D models?  Measuring arbitrary
dimensions *in* those models?  (scripted) Forms?  URLs?

Sadly, too few folks really leverage the abilities of the PDF container!

We routinely convert paper forms (e.g., from doctors, tax agencies)
into "fillable PDFs" so we can keep nice digital copies (instead of
filling them out in pen/ink and then scanning the results to save).

It would be silly for me to have to paste the entire source code for
a project/module into a PDF /as text/ and force the viewer to wade
through it to understand some commentary that I am making about a
portion of the code.  Or, to hear some audio samples of how certain
settings are rendered.

Instead, I can leave the document to have the prose explaining those
issues and attach or embed the rest so it is available to the reader.

I can click on any "component" in this model and see a description
of the associated "parts" on the right side of the screen.  Or, rotate
the model in X/Y/Z, zoom, convert to wireframe/outline, etc.

How would I convey to a READER the difference in synthetic voice qualities
corresponding to "creakiness", "breathiness", how the choice of glottal
waveform emulation affects comprehension, etc.?  It's SO much easier to
have audio IN the document, alongside the explanatory text!
