Well after wait for a much better browser from Microsoft, they deliver mostly crap. The only thing they really improved is that it now has tabs, slightly better security, a build in search box and alpha PNGs. Not very much considering how far behind IE compared to... well any other browser. I don't think this new browser will be putting Firefox under any time soon. Speaking of Firefox... You do have it doesn't you? What?!? You're not using Firefox? Well, it you like popups and viruses than by all means have fun with that. Oh yeah, by the way, all the new features of IE7 are currently available in Firefox. So what are you waiting for? Go get Firefox!
Update: Microsoft says that they are going to include a lot more standard compliance for the final version of IE. I guess we'll just have to wait and see.
