It's not everywhere because users don't realize they have it yet (the "goes in a cupboard" problem this article discusses). Login to your wireless router right now and set it up. It was, literally, one button on a DLink wireless router I used. Chances are your ISP supports it and it's ready to go for you right now. You don't have to (everything works by default with IPv4 right now), but why not? It's fun and you'll learn how it works, and it doesn't break compatibility with IPv4 access. If wireless routers enabled IPv6 by default, you would be using IPv6 and not even realize it. It's amazing how seamless it is. I actually had trouble figuring out if it was even working.
