IE7 Beta floating around
 

You can find it if you look...if you're curious enough to actually try it out that is. Haven't really used it much, just opened it up, opened a bunch of tabs...and took this screenshot, I'd like to actually think that maybe it'll be secure(er) this time around, though, at least they finally thought about it and added the tabs (for those that like to use them, which, I do).

does it have anything cool that firefox doesn't?

It has built in phishing detection, I know there are add-ons for firefox which do that. Besides that, nothing that comes to mind...I'm back in firefox atm, I'll fuck around with it some more, or just post a features page..
