Actually, I read it with interest. I am designing quite a bit of
electronics. A lot of it is single use, then "throw-away" these
days so long running times are not that much of an issue.
But selecting the right power connector is always a problem
I face. I often choose the 5.5x2.5mm barrel plugs, as they are
quite common on power supplies, but they are kind of suboptimal
when it comes to retentiony The Kycon 4-pole plug is slightly
better, but every and each power supply has a different pinout,
which means that I either need to design it for a specific power
supply or add 8 diodes to get the polarity right. 

I pondered a couple of times to use Molex Micro-fit connectors,
as they are cheap, locking and available in almost any number of
poles. The current and voltage rating hare high enough for almost
all needs (but not enough for 240V mains, even if it's rated 300V!).
And incidentally the crimping tool doesn't cost an arm and a leg.
But it's not really a connector one wants to use to power a device
in a proper housing.

Reading on what other people are using and what advantages/disadvantages
the different power plugs have is quite interesting for me.

So, please keep it comming!
