So a presentation program is a tool to quickly create something that sucks? I'm not interested in such a tool.

Well, as a matter of fact, on the few occasions where I had to give a talk, I did use LaTeX with the beamer class. I tried to do things with OpenOffice.org, but I found it hard to use and wasn't satisfied with the results.

If your presentation program forces you to use raster graphics, then I suggest you use another one. LaTeX interoperates with a variety of vector formats such as SVG or PDF. Also some programs (such as Gnuplot or QtiPlot) allow you to export the graph in PGF/TikZ format, making integration with LaTeX trivial.
In short, there are ways to make presentations that don't suck.
