I agree with the other commentator in spirit. Just because the spec is free doesn't mean it is suitable for web developers. The HTML5 spec should be written for browser developers.
For example, the C++ spec is available (although, not sure if its free, but imagine it is), but I'd recommend it to VERY few people. I'd much more likely recommend Lippman's text or Koenig's, even if there is a $20 price premium on those books.
In the same way, if this book distills HTML5 into what is necessary and useful for web devs then it is worth $20.
