The Bombe machines used to decipher Enigma are usually described as being electro-mechanical devices. Perhaps you could argue they were special-purpose computers of a sort, but definitely not the programmable, general-purpose machines most people think of when they hear the word “computer”.

The first programmable electronic computer was developed at Bletchley Park, but it wasn’t used to decipher Enigma.

The SR-71 is really fast and sleek, sure, but how can it be your favourite when it doesn’t even have a massive gun that goes BRRRRRRRRRRRRRRRRRRRRRRRRT!..?
