> I can always control at some level how those pixels are drawn How well does that work when your GUI must be shown in arbitrary devices, with arbitrary screen sizes and arbitrary resolutions? And how well does it reflow when the user changes the viewport size? In any case, the original post to which I replied was comparing HTML5 to the NeWS platform, which provided a unified UI stack itself, so you wouldn't be able to match the native behavior following that approach either.
