You’re reaching around the back of a computer and you can’t see the exact location of the mini-din jack, you have to angle the plug normal to the plane of the computer back (more or less), you have to center the plug (translate the plug horizontally and vertically) to align it with the jack, and you have to rotate it so the the indentation (and of course pins) align. But… My old computers all had a slippery steel plate surrounding the jacks, and the jacks had plastic centers aligned flush with the plate, having the plug overlap the steel plate never felt terribly different from only having the rotation wrong.
