With IPv6 when you think of assignment to end-user, it's better to think 
in terms of 'use case' rather than number of hosts within a single network.

As a residential user I might have wifi, voip, TV, CCTV,,... each of 
them can use its own prefix.

As a bare metal user in a datacenter , I might have different needs when 
I build any internal networks.

As a corporate user, I think this one is the more obvious.

The only end-user who might stick with a single /64 is
- 1 smartphone
- 1 VM
