It should probably be pointed out:
Asking for practical advice on choosing /48 vs. /56 on a residential broadband CPE is largely unanswerable.
Why?
Because I don't know of any residential broadband CPEs that support IPv6.
If one doesn't look then you won't find it.
I want to be wrong about that. Seriously. Send me a link to one. I want to be wrong. (And by residential, I mean a CPE/router/firewall that costs less than $150US.)

So I stayed on a small guest house on the southern outskirts of Toyko a couple of weeks ago and along with the luxury of getting breakfast with my $80 a night 9-tatami room, the complimentary wifi shared with 4 other guests had v4 and v6 provided via kddi residental vdsl. My hostess who was 75 if she was a day had email down pretty well but I wouldn't characterize her a technical user.
IMO, the only answers so far:
businesses get /48 dialup gets /64
(by default anyway; there are always exceptions)
