I don't use them, mostly because interactivity is so core to my work. I'm generally distrustful of vendors and people who let you "look but don't touch" at their work - I get suspicious that it would break if they let me really use it. I'd prefer to put up a real working model of a learning interaction so people can see how it works from the inside. From that point, you can always take a bunch of screenshots and animated gifs of the experience to put in a slide deck or video for someone so busy that they will only spend two minutes on it.
