Take a look at this keyboard. What do you see that is slightly off about it? It looks like an everyday QWERTY Keyboard, except it is made without an E, an A, a D, or an I. Are these the 4 most commonly used letters or something?
While there seems to be no explanation for the redesign, this keyboard would be a very humorous gag gift, or just a fun way to prank one of your friends by exchanging it with their keyboard when they aren’t looking. — Andrew Dobrow
