I disagree, I think that history.pushState is the most important thing.

  There's a difference between cool and important. pushState isn't that cool as we can almost do the same thing without it (#!), but web sockets are a whole new concept. That said, for sites that don't constantly update, pushState will be more useful than web sockets.

  ...because history.pushState is what makes it ok to use all the other cool stuff.
