Yeah, I think Rob is right. It's impossible to cover all points of the Canvas in one chapter. So more special book needed for this. I think the Canvas is one of the most used things of HMTL5 in the future. Not Flash or JavaFx, HTML5 is the future!
@Rob, you mentioned your new book (HTML5 in action), I think it will be great book, somekind like Spring in Action, but could you please say when you are going to finish this book? And will we have the opportunity to win a copy of this book?
