I wrote it to use with PadlockHack and EasyLaunch (both are free). With EasyLaunch you can start Shutoff! with one penstroke everytime andfrom every program and automatic shut off your device. With PadlockHacks smartoption your device is locked if someone uses the hardbutton to shutoff the device, but stays unlocked if used (by you) ... that way you don't have to unlock your device every time you use it and have a good security if someone other than you uses the device.
