Both HTML and XHTML are in sorry need of removing deprecated items while being updated to reflect the current practices of web and browser developers and remaining compatible with legacy Recommendations. The much more open and transparent WHATWG (Web Hypertext Application Technology Working Group), formed in 2004 to address this problem, and has been hard at work on developing a draft spec for HTML5 to update and replace legacy versions of both HTML and XHTML. The quality of this work has reached the point that Apple, Opera, and Mozilla have requested the adoption of HTML5 as the new 'W3C Recommendation' for Web development."
In the future, you're going to get computers as prizes in breakfast cereals.
You'll throw them out because your house will be littered with them.
