Just my opinion.. but a single input on a page doesn't convince. It's when trying to create an entire form on a page that the differences are more obvious.
Even so, it looks noticeably different in IE and, in fact, the submit button (which displays "Submit Query" and is therefore much wider) did nothing for me at all in IE9; the input-background is not pink. FF17 says "Please fill out this field" - it doesn't include the "dd/mm/yy". Added I am aware that not all of these points are directly relevant to HTML5.
Personally, I am not interested in debating the point - I'm just recounting my experience and thoughts. Besides, I am not rejecting HTML5 - I'm happy to use it where it is useful (autofocus, required..), but one cannot ignore the differences.
