Also, I'm pretty sure that, quite a while ago, the PS/2 ports did start 
getting made to work with either keyboard or mouse even though they often 
still got labeled as being just one or the other. And I can't think of a 
component in my system that isn't keyed but should be. Even IDE ports/plugs 
started getting keyed a long time ago. But yea, audio-in versus audio-out is 
still one notable case where you can put the wrong thing in the wrong place. 
Although, most speakers/headphones do actually work as low-quality 
microphones :)
