HTML5 native experience implies that Internet Explorer 9 was built with the platform in mind, and for Windows to deliver the most native HTML5 experience on the web.
The progressive step in delivering the most native HTML5 experience as supposed is in the support expected on IE10 platform preview, now available for download. Internet Explorer 10 directly trails the path of IE9, using Windows features devoid of abstractions, layers and libraries that slow down web experience.
'Native HTML5' is far more than hardware acceleration, as it incorporates general performance, and not just embracing HTML5 as a way of building native Windows applications. What differentiates Native apps from web apps? Browser-based applications is the basic differentiation, and you don't expect to double-click a document and have it launched on a browser to render the file on a website.
How Microsoft intends to implement such features are yet unknown, nor what the various types of applications needed to translate and feel like a native app. However, web developers will have a handful to offer, and as it sounds, may perhaps herald good tidings for the new standards, HTML5 and CSS3.
