Seen 'em
Seen 'em. Go to some greasy porn or pirate site (not that I've ever done that... oh no... of course not) in Ubuntu and be amazed at the appearance of "Windows" dialog boxes on screen, swearing up and down you must click "Yes" to continue, click to install flash (on pages with zero flash), update your video codecs, update chrome (even when I'm in Firefox), update my virus scanner, and so on.
Of course, this specific method of doing this does appear to be novel.
