When it comes to the browser wars, I've been a Chrome fan for some time now. I want two things from a browser: speed and real estate, in that order, and Chrome kicks ass over IE and Firefox on both accounts.
But to my surprise, I have to say I think IE9 just took the lead. Specifically, IE9 definitely seems faster to me when browsing deviantArt galleries, watch messages, and so on. I've never seen dA pages load so fast before. If you typically spend lots of time browsing here, and you're on Windows 7, I think it's worth checking out.
While you're at it, go check out this artist, who I think is really awesome.
