Then you don't have any prejudices ;) (no, IPv6 doesn't break your 
network).

If it's free (cost) and you have the time to set it up properly.

Yes, as others have pointed out.

What I didn't see mentioned in this thread is that IPv6 does not 
need/use NAT. Some users rely on NAT in IPv4 as some sort of protection 
(it is not, you still need a firewall).

When properly configured[1] with IPv6 all devices on your home network 
supporting it will be directly accessible from the internet (by design).

Your firewall rules may need to be adjusted to account for this.

[1] depending on your ISP and/or modem you might not need to do anything 
at all with most recent OSes in their default configuration.

Kind regards,
Andrei
