I don't see how Apple could get more "open" than what they're doing with Webkit and their HTML5 implementation. Let's take an example: CSS Animation. They have: * Made an official spec for a CSS3 addition, labeled CSS Animation. * Submitted the spec to be included in the overall HTML5/CSS3 document. * Wrote a reference renderer in Webkit that properly uses a vendor tag for non-standard CSS elements (as per the CSS spec). * Open-sourced it in Webkit. I don't know how more "open" you can get with Apple's HTML5. Somebody has to create the bleeding edge in order to get there. How do you think CSS3 supports the features that it does now like border-radius or RGBA? Somebody made it and submitted it. Just because Apple forces you download Safari for (presently) Safari only demos doesn't mean it's any less open. I know that Firefox is slowing working towards adding all the cool features. For example, the 3.7 alpha supports CSS transitions (the precursor to animations).
