I lived in the UK for four years. There's some things I miss from there:
* easy access to good fish and chips
* a dense railway network
* power plugs that don't feel flimsy
* power plugs that are easy to insert
* power sockets with on/off switches
* my friends over there
The European ones (Schuko, Type C, Type F, whatever) are often difficult to insert. The pins are often wonky, apparently due to the required tolerances being bad, but that's my guess.
