Peter Lubbers, Brian Albers, Ric Smith, and Frank Salim put together and excellent resource for powerful yet practical HTML5 code that can be used NOW. The book refutes the myth that HTML5 will not be usable until 2022 by going on and showing you how to use it today! By leveraging API's that have common browser support the effort is not purely academic. Although the code is targeted for a more advanced audience, an adept user will be able to glean plenty of information from the examples. The book answered many questions I had about the emerging HTML5 standards, and gave me some new techniques to implement. I recommend this book for anyone experienced with HTML who wants to start using HTML5 now.
