I work in an environment full of brilliant, technically minded people. Try as I might, sometimes I simply forget how little most people know about computers.
In IKEA, I saw a odd wire metal rack which mounted to the side of a desk and held a computer tower suspended off the ground. Why anyone would attach such an ugly thing to a desk is beyond me. What is wrong with the computer being four inches lower, on the ground?
Moments later, an young, female employee pointed to the tower rack and referred to it as a "CPU holder". Never mind that she was actually trying to sell this silly thing to someone, she just called a car engine by the name of a fuel injector!
