Yup, the fact is the US still has a sizeable reserve of 
unused/unallocated IPv4 addresses. However, besides the address space 
exhaustion issue present in the rest of the world, IPv6 has other merits 
as well, which are a real tangible benefit to all of us (some related to 
the huge address space, like simple prefix routing because there's so 
many space). I think these merits are underlit currently.

Yes, for instance, mobile devices connected to the Internet. The number 
of mobiles in daily use is surely so large, IPv4 reserves can't cater 
for it. Then, there's the booming internet media distribution market, 
which requires media playback devices to have access. With that, there's 
numbers of those 'business opportunities' that will thrive only if the 
Internet can sustain the number of devices connected. It's easy to see 
the 32-bit IPv4 address space won't suffice. Now, there are technologies 
like NAT, but they're just a hack on a standard that didn't cater for 
it. An ugly hack at that. Now for all those cost-conscious 
'decision-makers' out there, I'd like to ask if it's worth throwing 
money at making applications work with NAT each and every time you 
invent them, now, and in the future, on a regular basis? Or throw money 
at a new standard once for a prolonged period? I think the choice is easy...
