I am not too sure about addr shortage and thus can't comment myself.
But what we do know is that IPv6 provides a large amount of *subnets*
and each subnet (minimum recommendation being /64) already contains
lot more addrs than entire IPv4 space. So it could mean some new
possibilities down the road (e.g. certain companies using ipv6 for
product management, etc) as the technology changes.

Yes.. stateless autoconf by icmp and few others but I don't really care
about those personally myself.

Unmemorizable? I don't know about that one. I can memorize IPv6 addrs
much faster and better than IPv4 addrs. I know it may sound like a
paradox, but IPv6 addrs, once you get used to them, are neatly
organized into TLA->NLA and all the way to Site level.

Bad assumptions.
