Internet Explorer 7 beta

Microsoft is beta testing Internet Explorer 7.0 right now. While I'm a fan of FireFox, I'd still like to see how this software is thus far. Unfortunetly it's a selective beta which means it's not open to the public. And while I could Google it and find a copy of the software, it would; 1.) be illegal to install and 2.) I hear can't be un-installed if it has problems. Hopefully the second beta will be open to the public and I can give it a try.
