Sure, but the same thing is possible with a cheap 6-year-old sub-$50 
popular Linksys wifi router, see http://opensystems.wordpress.com/2006/06/01/linksys-wrt54g-ipv6-howto/
for example. The point is that it can be cheap, relatively easy 
and painless for users to upgrade.

Basically, it should not have to cost anything extra to set up 
new users for IPv6. The same hardware that handles IPv4 today
can be programmed to do IPv6.

Users don't care about IP geo-location or anti-DDOS measures, or
any of the other reasons you list. These are things content providers
care about, but they don't get to choose wether their viewers use
IPv4 or IPv6.

As long as a majority of users come over IPv4, better anti-DDOS
measures or anti-abuse procedures for IPv6 are not going to make
any difference. "When you DOS my site, please use IPv6, so we
can better find out your location and more effectively block 
your IP address."

Users are going to drive adoption of IPv6, if and when they
find a "killer-app" where IPv6 can provide usability that (heavily
NATed) IPv4 can't. This could be better file-sharing tools, lower
latency online gaming, better long-distance video-calling or whatever, 
as long as the benefits will be worth the relatively small 
(<$50) investment of money and time.

For content providers, as long as 90+% of the net is IPv4 only and
essentially nobody is IPv6 only, providing dual-stack support is just
adding cost for little or no gain in viewership. Content providers
often depend on dozens if not hundreds of pieces of hardware and
software to provider their services, so supporting IPv6 is vastly
most expensive than it is for users to take advantage of it.

In my case, the upgrade to IPv6 was free. There must be many more
using an Apple router (any model, Express, Extreme or otherwise)
that can upgrade to IPv6 for free. However, I can't list any benefit
from doing so, except from going to test-ipv6.com and seeing a 10/10
score. Basically, you have to be a geek to be interested in IPv6.
That's got to change, before there will be any meaningful shifts.
