We all love owning and using our iDevices, probably a bit to much in some cases, but at the end of the day when the sun goes down there comes a point where we just want to slip under the covers and have an uninterrupted nights slumber. Depending on what apps you may have installed on your device, it could be set to push alerts for pretty much anything meaning that peaceful nights sleep could be well and truly thrown out of the window if you forget to flick that silent switch.
