    Working Draft is in Last Call
    Some parts of the Draft are more mature than others.
    Increasing number of devices and browsers feature partial implementation.
    You don’t have to wait to start using some aspects of HTML 5!
  • Downsides
    Development of HTML5 specifications is slow and is subject to change
    Real time video streaming is not supported nor is the full screen video
    HTML is not an XML standard, so may be incompatible with XSLT & MathML
  • Future
    Even though it is far from being finished, a lot of developers have started use HTML5 features that are being currently supported by the browsers.
    It will eventually evolve into a programming platform.
    There is a possibility that it will replace Flash & Silverlight.
    Search Engines will give better results.
    Web Pages will be able to load faster.
