Just my .02$

- examples of pictures Excel is unable to produce
  (Boxplots, lattice graphics, see the recent discussion here
  for examples)
- links to databases and Excel
- an example of the (l)apply function for programmers
- links to GIS (GRASS, ArcInfo) for Geographers
- examples of spatial analysis package
- compare the price tags (students and scientists can use
  it (legally!) everywhere without going to jail 8-),
  no dongles, licence servers and limitiations of the size
  of data sets.

I would focus on the workflow of data in science and
demonstrate how this is handled in R. Perhaps
the outline should have less science and more marketing 8-)

Greetings,

Georg
