I have a distinct memory from my childhood. See, I was taking piano lessons but I wasn't practicing regularly. Finally my dad points at a guitarist's well worn acoustic guitar and tells me "See, look at that woman's guitar! Do you think she had a machine to wear down that guitar? No! She practiced! That's how she got good!"
Handling audio in such a way that both professional audio-centric users and casual users wondering why they can't hear the IM beep while playing MP3s are happy is actually fairly tricky. In the early days it was, naturally, quite easy. Your application wrote to the hardware. The hardware reacted pretty much instantly. No biggie. But multitasking threw a wrench in that.
