I suppose that "Google 2.0" includes a few more tweaks besides just the typical universal search. Google's revamp which was first covered by Danny at Search Engine Land has more than just universal search: the search engine has been resdesigned and now uses CSS.

Indeed, it's rather nice, but I'm still getting used to it. :)
