Earlier quoted context omitted.
There's a light for the camera, they should just add one for the microphone.
While acceptable for most paranoid users, the indicator light isn't as secure as a physical switch. For some devices (most notably 2007/2008 era MacBooks) the controller can be manipulated to enable the camera without giving any visual indication via the light.
