What isn't really helping adoption of IPv6 support now is attitude of some ISPs. There are ISPs that use migration to IPv6 as a way to tighten their reign over users. They will give you DS-lite only (ok...), but with /64 (no /56, no /48). They will force their router on you, where in past with IPv4 they would provide an option for bridge. Their router cannot do PD (if it had more than /64, so maybe that's the reason why they do not provide that), so if you want a virtual net with VMs on your machine, you are going to waste your time playing around with IPv6 NAT, which doesn't work correctly anywhere. You can't control RA/DHCPv6 on the router, you cannot really control firewall rules. Suddenly, the ISPs has ony free reign over your network, but also over policies on your network. So for undemanding users that's fine, it will work with Facebook and Netflix. For a power user, the IPv6 offer is unacceptable, not because of IPv6 properties, but due to limiting implementation that the ISPs force.
