Google Prefs for Mobile Devices and XHTML

I'm on the Google Preference page from time to time, and noticed something new today.  Google now allows you to output search results in HTML (default), XHTML or for PDAs!  Or does it?  I just went back to grab a screenshot of what the different outputs would look like, and the setting is gone.  Weird.  Something to look forward to I guess.
