Almost always when I'm in a country that does not have European (CEE) plugs and sockets, I feel uncomfortable. All CEE combinations have very solid touch protection. It's almost impossible to touch a metal pin of a plug when it's so close to the socket that it might have contact.
When I the see the "flat" style sockets plus the full-metal pins I wonder if it's just a bad feeling or if way more people gets accidentally electrocuted with that kind of plugs/socket than with our CEE types.
