I despise the beep.
God forbid someone might want to turn on the PS3 while someone else in the house is sleeping -- a regular occurrence in my apartment, where my beloved partner sleeps like a normal person and my night-shift-working self is occasionally awake at night and wants to play a game.
It's ridiculous.
And these days seemingly everything beeps. The PS3, the fan, the space heater -- all things that you might want to use when another person is sleeping. I was able to turn off the computer's startup sound, at least. (Haven't figured out how to turn off that sound that plays when you plug the iPhone into the Mac to charge it.)
A peaceful and quiet environment free of high-pitched beeps; is that too much to ask?
