Microsoft and the Internet Explorer team just released IE8 beta 1.

You can download it here: http://www.microsoft.com/windows/products/winfamily/ie/ie8/default.mspx

Just a warning, it is extremely buggy.  I’ve found a few things so far.

IE8 beta 1 does not work with Netsuite.com

IE8 beta 1 displays certain text really fuzzy.  I believe it has something to do with the clear type feature.

IE8 beta 1 changes the default font type in Outlook Express 6.
