Interesting. Are you using Chrome for Windows, perhaps? I'm using Chrome for Mac (5.0.375.29), and all that happens when I click "See it in action" is that the page is scrolled to the top.
Doesn't work for me (Chrome nightly build on the Mac). Didn't work in the Chrome mac production build either.
For anything web related, no matter how slick it is, if it doesn't work on a few browsers, it won't get adoption unless you run a website that only caters to specific browsers on a specific platform (like a website that can only be accessed on an iPad device).
But this thing looks really nice. I love the website design, as well.
