It isn't? That's strange. Why would they do that, security reasons?

About JS performance: Might be important to you as a gamedev, but for the overwhelming majority of today's web apps this shouldn't be an issue anymore.

That being said, I will probably still switch back to chrome when they get retina support. The interface is just cleaner and it has more intuitive developer tools IMO (safari's are more powerful, but chrome's do have everything I need and are easier to navigate).

Chrome Canary has retina support if you want to get a sneak peak at it. The problem is Canary crashes OSX often.
