Since a lot the html5 modules (and related standards) are still being worked on, we can't expect every tech demo of the new features to work in every browser. Apple wanted to show some very shiny html5 demos and that is fine. There is a good chance that everything shown there will be working across all the major browsers in a not too distant future. (Yes they have have to loose the vendor prefix -webkit first, but that is actually the recommended way to use non-finalized preview features of the emerging standards). I see this as Apple pushing the html5 wagon forward, the same as the other major browser vendors do. Have you tried Internet Explorer 9 Preview demos in other browsers? Finally the html standard is moving forward again after years of standstill. How anybody can complain about that is beyond me. Cheers!
