Why don't you program a webbased email frontend like gmail without
javascript? Good luck!
Well, you will probably argue that nobody needs those kind of services, since
you can check your mail with desktop mail client...
that's true, but people *want* them and they expect this kind of
functionality in a webbrowser.
In a CMS they also expect a handy image uploader that can handle drag and
drop, maybe allowing you to sort the uploaded images via drag and drop and so
on.
Impossible without js.
I'm pretty sure that the only reason you never heard "a single example" is
because you always refuse to accept those examples as valid ones.
