More and more smartphones are sold every day. More tablets with 3G/4G internet. More laptops with either wireless internet built in or with a dongle.
Few of those devices actually need a static IP address. ISPs can NAT or 6to4-tunnel the hell out of smartphones and wireless dongles, and only a small minority of tech-savvy customers will care. The situation is obviously suboptimal compared to one-IP-address-per-device, and I would hate to pay extra for my own IPv4 address(es), but many more devices
can be accommodated without using additional IP addresses, and it will be done if necessary.
It's alarmism like the following that I disagree with:

My point was when IPv4 addresses run out, and all new connected devices have only 1 option (IPv6) and IPv4-only devices are in a world of hurt. Performance will severely degrade over tunnels that will most likely be offered by ISPs (many of which have their own technical limitations and security implications that most web developers have yet to consider), and as Google has proven time and time again in studies, speed matters to visitors.
This is pure speculation. Although deploying NATs and/or tunnels in a large scale will have hitherto unknown performance and security implications that need to be worked out, the issues can and will be worked out. I see no evidence to support the claim that the average customer's online experience will be "severely degraded" during the transition from IPv4 to IPv6. Maybe it will add a few more milliseconds of lag when you're playing your favorite FPS, but if you have a problem with that, you can always pay more to have your own IP address. There's nothing new to the story; it'll be just another chapter in the history of ISPs ripping us off at every opportunity.
