For some unapologetic gender stereotyping (it's true I tell you), it's a boy thing. A woman, placed in charge of the design and implementation of a device will install a simple on/off switch and move along.
A boy, on the other hand, will look at the on/off functionality and design a control panel with three dials, six buttons and two LEDs with a removable faceplate. On being asked how to turn the device on, the instructions will be: turn dial 1 to 4, dial 2 to 6, and leave dial 3 at zero. Hold buttons A,B, and D simultaneously until you hear a 3-second beep and the second LED lights up and then turn dial 3 to 2 and dial 1 to zero. If you hear a two-second beep, keep holding buttons A, B, D and also C until the two-second beep sounds and LED 1 lights up. Then turn dial 2 to 10 and the other dials to 0. If the LED 2 lights up and there are two two-second beeps, then remove the faceplate and use a type of screwdriver you don't have to turn the actuator one quarter turn clockwise and then replace the faceplate and repeat to turn the device on. For more information, please consult the badly translated Chinenglish manual that we've included on a 3 inch CD that would not have played even when people had optical drives.
Of course, you will have the modern alternative of an app with myriad options, so you can be frustrated remotely. And this is why men shouldn't be put in charge of anything. They'll just festoon it with needless buttons and options.
