That's the problem: IPv6 is not a "product". It's plumbing.
People do not ask for "IPv4" either, they want "Internet".
Now, the problem here is - using IPv4-only, "Internet" is going to be
expensive and increasingly fragile and non-working in the not-so-far
future (multiple layers of NATs, half of those overloaded at peak
times, etc.) - so to be able to sell the product "Internet", we all
need to move to new plumbing. IPv6.

Don't *ask*, just *ship* - make it part of the standard package, and
just deliver it. (I'm not claiming we're fully there yet, but for example
all our mail products [finally] have IPv6 capable MXes now...)

If you count percentage of webservers, we have a long way to go, yes.
If you count percentage of *traffic* that would use IPv6 if it's
available at the client machine (and it's not a dumb Apple device),
you'll see 20-40% due to google, youtube and facebook being v6-capable
today. That's a significant load reduction on your carrier-grade NAT
box, and thus actually helps lower costs, while keeping the service
up (no 3rd party NAT in the path).
Servers will, unfortunately, have to have an IPv4+IPv6 face towards
"the Internet". Clients, OTOH, will *have* to move to IPv6+NAT64 or
IPv6+NAT444 in the very near future, as there are just no more IPv4
addresses in Europe and Asia to permit DSL, Cable, 3G providers to
grow any further.
have you enabled IPv6 on something today...?
