So that's, what, another few months? Of course, there are still many other huge blocks of unused space. But eventually we'll either finally make the jump or everything becomes the NAT setup from hell, as it is today with mobile connections. Speaking of which: I believe mobile internet would have been an excellent opportunity to ship IPv6-only devices to a mass market and that in turn would have resulted in a widespread adoption effect. Oh well...

Some carriers (e.g. T-Mobile) are discussing going IPv6-only with NAT64+DNS64 to access IPv4 servers, but there are a few cases where this is worse than IPv4-only with NAT44 and very few cases where it is better. So you're basically proposing to make phones worse.

and that in turn would have resulted in a widespread adoption effect.

I don't see why.

I'm proposing to make phone worse by suggesting my wireless broadband should not be behind NAT? How is upgrading this infrastructure worse than the patchwork disaster we have now? Can you give some examples?

I don't see why not.

IPv6 is lacking critical mass. The mobile space is fast-lived and semi-organized enough to serve as a vector to push fundamental things like these through into general adoption.
