I am actually using LaTeX to write my thesis, but I am still learning it and don't really have the time to learn how to do a presentation with it (but it is on my to-do list for the summer).Off to the side, I've heard that Prosper works well, and I believe you can generate a presentation that uses Acrobat Reader (at least, that's what is used as a demo of its abilities). I don't know what the learning curve is, though, or whether you are into LaTeX/LyX.
