If you're like me, you had no idea there was so much HTML 5 already in play.
Yet Google, Mozilla, and Palm gave us all a big whack upside the head this morning. As Shakespeare said, "The hot blood leaps over the cold decree." The technology is here even if the standards committees haven't caught up. Developers are taking notice of these new features, and aren't waiting for formal approval. That's as it should be. As Dave Clark described the philosophy of the IETF with regard to internet standardization, "We reject: kings, presidents, and voting. We believe in: rough consensus and running code."
Support by four major browsers adds up to "rough consensus" in my book.
