Yeah, I am actually using the IE9 release candidate right now, and it is much nicer than IE8, in fact, I'd say it's at least on par with Chrome

(never thought I'd say that about IE). It doesn't quite have all the bugs worked out yet, for instance, the new Flash Player that was designed with IE9 in mind (it supports hardware acceleration) doesn't want to play Pandora, but it will play YouTube and most other sites, but it's not a final release yet, so bugs are sorta expected. If I want to listen to Pandora, I have to use Chrome, which I will usually use if I know I'm going to be using the flash player.
I would be using Chrome right now, but I heard about the IE9 RC and heard that it was actually good, so I've just been giving it a spin.
