I use LaTeX a lot and nearly exclusively, however for presentations I try to use HTML. I rarely get to do it, because work usually requires me to use certain templates.
Handwritten HTML is just as nice to version control. I can embed rich media stuff easily. I can use transition and other effects (in the rare cases where they actually make sense). I can embed interactive things, which is better than alt-tabbing somewhere else. I can create a pdf as fallback as well.
