I was reading about Typotheque's forthcoming webfont delivery service here: http://www.typotheque.com/site/news_details.php?id=164
And the author states that 'The @font-face rule is supported by Firefox 3.5, Safari 3.1, Opera 10, Chrome 2.0 and Internet Explorer 4.0 and later. Our system is thus compatible with more than 95% of all browsers in use.'
I don't believe that Chrome or IE do support the @font-face rules. Does anyone have more information on this?
