I ask: Will USB ports be de rigueur 30 years from now?
Plug ins are cheap. I'd prefer to use them.

I don't know the answer, but USB is certainly here for the
next five years, so, for the bedroom and office, where you
are very likely to plug in a USB-powered device, it makes
economic sense (at least to me), to pop in a 2-port 20-Watt
outlet in key areas.

Besides, the outlet actually costs (slightly) less than a
similar spec'd external charger, so, if you need a charger,
and it's for a static location, I don't see the advantage
of the wall wort style charger over the receptacle style.

I guess nobody knows of a better one than the one I found
(which is surprising), so, I'll get the 20 Watt outlet that
I had found by googling. They don't seem to sell it at the
box stores though, so, I may have to order online.
