Impress.js is an awesome piece of tech—but I wouldn't use it for a presentation:
There's just a very fine line between over- and underdoing a presentation. It's never good just to dash off a presentation with lousy layout and design but it may not be beneficial to overdo a presentation as well. Too much FX and animations makes you at a certain point needy: "Look what I did to impress you", "Look, another animation!", "How nice, isn't it??", "And here another 3D effect, awesome isn't it? I spent the entire day to make the rotation perfect, just for you because I like you!". After the 5th animation the viewers think you are a needy guy, needing approval, spending to much time on design than content and having nothing to do.
Different with pure web presentations for a large audience, then such tools are nice, but I don't know if they convert better than a gold old landing page.
