It might very well be that manufacturers prefer to use the C7 and C1 in
countries where 100-120V is common. A lot of the equipment with these
connectors is from Japan-based companies, although the bulk of the
equipment itself is probably made in China now. The C7 (non-polarized) is
still very common with laptop power bricks too, though.
I have lots of plastic bins full of C13 cords, and at least one filled
with C7 cords. In fact if you happen to need a C7P with a polarized NEMA
5-15P and have trouble finding one, I've got lots of extras left over from
when I used to service consumer A/V gear (I doubt these would be of much
use in the UK, though). Another very common use for the C7P cords are
camcorder battery chargers.

Interesting. I wonder if many of the laptop suppliers included different
power bricks there? Lenovo, Dell, and HP all use the C5/C6 with many of
their US marketed laptops.
No...I did mean C6 (3-pin) since Jim mentioned
asking PSU builders about
the C13 (C14 inlet).
Things may be different in the US, but C13/C14 is the most common in UK
and Europe, and C5/C6 is relatively rare, which makes them more
expensive here. The C5/C6 is
now very very common with newer laptops and IT equipment.
In the US, the C7P polarized version is extremely common with consumer
home audio equipment. Both the C1 and a coupler similar to the C1 that
is more rectangular with rounded corners (still 6.6mm c-c) vs the more
oval version in the standards are also very common with battery powered
portable radios and similar that also have an internal power supply.
I can remember only ever once seeing a C7P, and although I've seen, and
possess, some C1 cables, I haven't seen any new equipment use them in a
couple of decades. Again, possibly a difference between territories,
but I imagine the cost difference is very small. The space difference
certainly is. Another factor, at least here, is that C5 is so common,
people have cables going spare all the time, and that makes for a
self-perpetuating or even escalating commonness. I bet we both agree that anything from IEC 60309
isn't required here,
though :-)
IEC 60309...lol. No, I don't think a C64 PSU will require /that/ much
current. I imagine someone has used a NEMA L5-15 or L5-20 with a C64 PSU
at some point though ;)
