It is indeed interesting. Some sites even let you view their content without JS, registering/subscribing, and/or revert back to something approaching an unstyled static site without showing any ads, sidebars, or other useless content.

To add to some of the other experiences here about no-UA: I've tried that before too, and it was notably worse than pretending to be Google; lots of sites just return "Internal Server Error" or similar messages.
