If you can’t wait to get your hands on Chrome for OSX, go download a Chromium nightly build, unzip, and copy to your Applications folder.

At first glance, it doesn’t appear much different from Safari, which isn’t too surprising since they’re both based off the the same layout engine (WebKit). The real differences are just going to come in the skin (which is pretty similar) and the JavaScript engine (Chromium = V8, Safari = Nitro, formerly “Squirrelfish”).
