All,
I just installed IE7 Beta 2 this evening. Was curious to see how it works. It is really nice. Fast ... tabbed browsing, the works. Really slick. Give it a look. You can download it here.

Right now it only works with Windows XP/SP2. If you're running that, you'll like it. I haven't run into any problems with it as yet.
