The holes in the pins are for a sprung copper contact wiper inside the socket that has a detent bump moulded into it to match the hole, providing a away for the plug to be retained.

      Power plugs have always been one of my pet peaves. The Brits do seem to have the most 'feature rich' ones that I have seen but at the cost of bulk.

      I always thought that the style used in North America was a reasonable compromise. If the device does not have a fuse itself, have a fuse in the plug itself. If the polarity does not matter, then have both prongs be of the same size, otherwise have the prongs of different sizes. If the device needs a ground then include a third ground prong. Another nice feature is that when a ground prong is used, it is longer than the +/- prongs so that it is first to make contact when inserted and last to lose contact when removed.

      It is true that they tend to fall/pull out easily and it is annoying that (especially for bricks) both +/- prongs can be easily exposed at the top. But when we were having our new house built I made sure that the builders put in all of the wall sockets side ways with the hot prong at the bottom. This solves the problem of both +/- prongs being exposed at the top and the plugs should not fall out of the sockets as easily.

      Some continental European sockets rile me up the most. Setting aside all of the minor differences that happen between some groups of countries that make them mostly compatible with each other but enough not so to pester me, the ones where the ground prong is in the socket itself are fundamentally flawed. You can easily plug a device that requires ground into a socket that has no ground prong! Also there is no way to differentiate polatity in a plug without ground and the sockets are too wide for no real reason that I can think of. There are some nice ideas there though. The sockets tend to be recessed and most plugs have prongs that are insulated a portion of their length. These two features do well to limit the exposure of the +/- prongs.
