Well, I've used the checkbox trick and stuff similar to that slider control on real sites. Much better to do it that way than to mess around with a bunch of extra Javascript code. But usually, browser compatibility is the biggest reason stuff like this isn't so common in production environments. A lot of large companies use outdated browsers that don't support much in the way of modern CSS or HTML 5 stuff, and they don't usually like being told that their CSS only tab system or progress bar doesn't work in their browser cause they're using IE8 or something else that's equally outdated. But I have used this sort of stuff before on real websites and applications.
