IE8 beta is going to be available for download starting today at 12:00 PST. Matthew Lapsen from the IE team gave me a spur of the moment demo for you all showing us some of the core features that power users will enjoy. Keep in mind that this is a developer preview of IE8, so the way it looks may change a little.
A couple highlights I think you'll really like include Activities and Webslices. Activities include doing a contextual search from something highlighted on a website. Webslices are the ability to track a specific section of a site, like a custom RSS feed. So you could make a button on the top of your browser that tracks an eBay auction or the status of our friends on Facebook.
