Consider an auto company network. behind firewalls and having thousands and thousands of robots and other factory floor machines. Most of these have IPv4 stacks that barely function and would never function on IPv6. One company estimated that they needed 40 million addresses for this purpose.

2) Anyone care to guess how much network gear is deployed that either won't or can't be upgraded? i.e. Old cisco gear without the RAM and/or flash to handle a newer code train...the old one in use long since unsupported, or gear from vendors that no longer exist? As long as this stuff generally works, nobody's likely to replace it.
