It's good to learn, because it will become more common as time moves on, particularly if you get into the datacenter/cloud/ISP industry. It's less important for the general home user, but it is important to understand how it works and how to use it safely.
Just treating it like IPV4 with more address space is dangerous though. you need to think differently about security and firewalls as it is as if every device has its own dedicated WAN address and could be open to the internet without you knowing.
Indeed it is good to learn: ipv6.he.net/certification is a free course everybody should take the first 2-3 levels of.
The login credentials you create for that website will allow you to login to their sister site tunnelbroker.net and claim a /48 delegation for your DDNS tunnel, also free, to promote the changeover to v6 from v4, especially for people with dynamic WAN IPS from their ISP and no IPv6.
Can confirm that HE course is good. They've even sent me a free t-shirt after I've completed it.
