As a pianist, latency of 20ms makes an electronic keyboard instrument unplayable for me. I wasted lots of time messing around with different drivers for soft synths trying to get below that number. 100 ms is a lot. In audio, a 8ms delay has an effect you can clearly hear, and can be used to "widen" tracks or simulate stereo from mono sound sources, since 8ms corresponds roughly to the amount of time it takes a sound wave to travel from one side or your head to the other.
