Internet Explorer 9 or IE9 is simply magic and launched today (Sept 15, 2010). Download it from here at http://windows.microsoft.com/en-US/internet-explorer/download/ie-9/worldwide
Lots of canned demos are at http://ie.microsoft.com/testdrive/. I personally liked the HTML 5 power http://ie.microsoft.com/testdrive/
