A basic understanding of what an IPv6 world will look like really didn't click for me until I read the IPv6 Address Planning book by Tom Coffeen. Before that, I really just saw it as IPv4 with longer addresses.
Once you dig into the details, you come to the realization that it's a nearly complete reinvention of IPv4. Network planning looks quite different (especially when it comes to subnets) when you plan them with only IPv6 in mind.
Earlier this year, I was like:
"Wow, Comcast gives me a /60! That should be more address space than I could ever want or use."
Now, I'm thinking:
"A /60 is way too limited, I wish I had a /52 or a /56 instead -- why is Comcast so restrictive with giving out address space?"
I'm currently reading the IPv6 for IPv4 Experts book to try to fill in more details:

The more I read about it, the more I feel like I have a long way to go before I really get an intuitive understanding.
