TeMPoraL's comment comes close to my response, but it's not quite what I'd say: A slide deck is a visual aid. Its only purpose is to be a visual aid. If you want your audience to take a physical memento away with them, don't be lazy: make a separate, physical memento designed to be taken away with them. Your slide deck should be useless after the fact, just like a bullet shell casing is useless after you've fired the bullet. When you make something, make it with a singular purpose in mind and make it fulfill that purpose well. IIRC, Presentation Zen covered this fairly well; in fact, I'm pretty sure Garr Reynolds is where I got this notion to begin with.
