As amazing as the web is, its potential is immeasurably greater. Internet Explorer 9 was designed to let that potential shine through. Click below to see how developers and designers are creating a more beautiful web using HTML5 and advancements in Internet Explorer 9.
They also state, "A focus on HTML5 and modern standards enables the same markup across browsers." A little late to the party and a seemingly Windows-centric vision of 'standards' (proprietary, as in the past), in my humble opinion. I should note that both Apple (Safari) and Google (Chrome) also seem to have self-centered visions of the web (and standards) lately, each as if HTML5 was their own baby.

If the current Web is like a giant text file - which you can search for instances of particular words – the Semantic Web would be like a database, where every item of information is categorized, and new queries can combine categories in any imaginable way. You could, for instance, search the Web for a restaurant within a mile of a railway station in a town with a theater that offers vegetarian lasagna and at least one lamb dish. And if you wanted the restaurant’s menu, you could pull up just the menu – not page after page of review sites that happened to use the word "menu."
It seems like Apple is using the same sneaky marketing tactics as Microsoft does with its HTML5 demos page - which doesn't really use any HTML5 either. This similarity is hardly surprising considering both companies are pushing a non-Free patent-encumbered codec for HTML5 video.
