SuperPreview: IE6,7,8 to test my web apps

I found this new web app browser test tool ships with Microsoft Expression Web 3. Its standalone version is now available for FREE.

One of the cool things that I noted about this tools is that, now we can test IE 6,7, and 8 version on a single machine and no longer to have a VM, or to have another blocks in order to compare versions between them.
