If you're feeling particularly bold, you can venture over to the Internet Explorer page and download the final release version of Internet Explorer 7, which became available to the general public yesterday afternoon.
Although the Windows machine I have at work is a pretty nice one (developers are assigned machines with the same specs), it's largely relegated to Windows compatibility testing and a teensy bit of .NET development. Since I don't store any crucial files on that machine, I thought it would be the perfect guinea pig on which to test IE7. Over the next few days, I'll report my experiences, complete with screenshots.
Here's a screenshot of IE7 showing the Global Nerdy site. It's still not gettting the CSS layout right; the page is still flush left when it should be centered (Firefox and Safari render it properly).
