Apple dropped the ball with their HTML5 demos

A slight correction for the article:

They say, "You’re not going to win me over if I have to own a Mac or use a nightly build to see something," but if you have a Webkit nightly on Windows you'll still see that same message telling you to use Safari on OS X.

So, basically you'll need a Mac to see any CSS 3D transforms. It's because that portion of Safari relies on the Core graphics framework.

I get 113 out of 160 on my Safari browser from html5test.com.
