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.
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).
edit: Actually now I'm using 5.0.375.29 beta (I just upgraded)
and it's still pretty much working the same way
