I wonder if they could add a new feature to throttle the phone's ring volume based on the ambient background sound level. It seems like a mobile phone should sample the background sound for a second or two prior to unleashing the ring tone, and thereby adjust its ring volume to be nominally audible, rather than blaring loudly and annoying everyone in an otherwise quiet room (or lecture hall). One might not want this feature if the phone was buried in a purse or briefcase, but it would certainly be a nice mode to have if the phone was worn on the belt or placed out in the open. Perhaps this feature is already available on some phone models...anyone familiar with it? (I apologize if this is considered off-topic for the list.)
