I'm not sure I agree that the above assertion is necessarily true.

In particular, Powerpoint provides a lot of snazzy animation-oriented
features that you or I could probably care less about, but that many
sales teams, etc. could not leave without.

OTOH, Powerpoint obviously does not provide good maths support, and does
not provide a good model for converting content to presentation (as Norm
points out). So it really depends where your values are at. But in
general, I would not consider your inequality to be accurate.

Technically, I believe PDF does support snazzy animations, through the
use of embedded JavaScript, so you could embed the appropriate PDF
information into pdfLaTeX-specific documents, with a lot of effort.
Alternatively (and much better), someone could write a tool that does
this for you, which would probably make

  LateX + Prosper + ??? >> Powerpoint

(double angle brackets being, "much greater than").

In general, I heartily agree with this. However, I am noticing a trend
in GUI-based Linux apps to depart from this most excellent philosophy.

I also really think Mac OS X developers should get into this idea.

One of my favorite pipeline examples, though it is now fairly obsolete,
is the one that the Dragon Book claims to have been typeset with. I
don't have the book with me at the moment, but it was something on the
order of

  pic doc-source | tbl | troff

The convention was to embed code in the "pic" and "tbl" languages into
the source troff document. running pic on the troff source would replace
the embedded "pic" statements with corresponding troff code, outputting
the rest as-is. tbl did the same thing with "tbl" code, and then troff
would typeset the results. BTW, TeX users who are not aware of pic
should give it a look; it's a rather ingeneous, though fairly basic,
language for describing technical illustrations in text format.
