To be fair, I am one of these people who would prefer their gadgets to please shut up until they are either directly asked to 'speak', or need to report a real problem... start up tunes of any kind tend to annoy me, I usually KNOW that I just pressed that power button. So if any quad designers are listening, please cut down on the confirmation beeps. Only blind people need those, and not many blind people would fly quadcopters, right?
