Prototype slimline UK plug
This is a brilliant bit of design. I find US and European 2-pin plugs rather flimsy (they often feel as if they will pull out of the socket accidentally with little provocation), but they have the advantage of being small and having a relatively flat profile. UK plugs are solid and secure but relatively gigantic. Also, if you've ever stepped — bare-footed — on to a UK plug with its pins uppermost, you know how painful it can be. I love the fact that the unfolded plug also has the advantage of a ring-shaped handle on the back, which would make removal much easier for everyone, including people with arthritis or other conditions which lower dexterity and hand strength.
