i dont have it. is it that cool.. that i need it?
you really don't have it? it's almost like the Internet isn't useful if you don't have it. you need it that much.
it's just a toolbar for searching and stuff.. hmm.. i'll put it on at home.. see how it works out.
does more than that. blocks popups, as thatdarngirl said, keeps your search history, let's you click on each keyword to search for it within the current page, highlights the keywords on the page, easily links you to google's cached version of a page, let's you traverse up the directory structure of a site real easy, easy to search google groups, image, etc
