Even though this is a book about HTML5 for mobile devices running iOS and Android, because HTML5 is a specification that's still under development and is not expected to be complete before 2012 or 13, it's important for you to know about all the tags (both current and future), and how they work on other platforms and browsers.
     The reason is that you are very unlikely to want your HTML5 web pages, web apps and device apps to work only on iOS and Android, because being HTML they will also display on most other devices too. Therefore this chapter dwells more on what HTML5 can do, period. Rather than just what it can do for iOS and Android.
