They are typically a solid moulded plug, so less components to corrode or wear out like the fuse holder/fuse itself.
So are ours - excepting the fuse, which I've seen wear out or corrode, uh.. not yet!
No need to worry about fuses (particularly of the wrong rating). Over-current protection here is typically built into the product itself AND at the switchboard (which also have RCDs).
Somewhat valid concern.
No need to worry about loose or incorrect wiring inside the plug, or broken strain relief.
Strain reliefs fail on moulded products too. So do crimps, solder, and ultrasonic welds inside them.
You can pull them directly out of the wall and break the circuit but pulling directly on the cable. Either through laziness or in an emergency.
This is precisely why strain reliefs fail, and is a practice which encourages unnecessary wear and tear and increases the chance of a fault in the plug or socket.
Whilst right-angled plugs do exist, they aren't common. The risk of stepping on the pins of an up-turned plug is negligible.
And the profile of the plug sticking out the wall is higher. Downside. Don't leave cables on the floor.
But it is also funny that he discards history somewhat. Early sockets did not have the child protection. What I can find about it is 1928 for the first to arrive.
That's quite interesting and also quite irrelevant, because BS1363 was first introduced in 1947, with shutters.
You will note that a lower rated plug will always be able to be plugged into a higher rated socket, but not the other way around.
So much for that overcurrent protection, eh?
Wow, that turned out to be a big wall o' text, SMF quote function is not friendly.
