One doesn't follow the other. It's short sighted to view the network
world in terms of the desktop computer. Specialized devices are a
scenario where IPv6 makes sense. Not all the world's computers need to
have IPv6 connectivity for me to want one.

I can get to my network over IPv6 today. That's meaningful to me. For
the sake of argument, it doesn't matter that I also have IPv4 access. I
can serve ISP services today to IPv6 only hosts.

That's certainly a valid point.

I guess I'll have to disagree with you there.
