> (slightly more) dangerous 230 to the much safer 110 should be considered as well...

Thanks, I prefer my kettle to boil in 3 minutes, not 30.

And 110V is still way more than any "non-lethal" voltage.

Considering what the most deaths from the contact with the electricity is the result of doing something extremely stupid - I don't think it would make a noticeable difference. More so, knowing people it would make more deaths, because "it is safer now!".
