Wait, you mean you haven't downloaded it yet? Why?
It's leagues ahead of IE8. And having tried Firefox before, and refusing to allow anything Google on this computer (besides Google Talk and GMail <<), and I don't even have Quicktime on here, I'm not going to try Chrome and Safari. So yeah, don't waste a comment saying I should go to that.
But I will say this, give IE9 a try. You'll be pleasantly surprised, I promise you.
Now, if you HAVE gotten IE9, disregard this rant and continue enjoying it.
