Camera vs. External Recorder

What are the benefits of recording audio on your camera vs. an external recorder?  Why would you want to use one verses the other?

    The benefits of recording audio on your camera are that it's an easier and cheaper process. As the sound is being recorded with the video, you don't have to sync the audio in post when recording on the camera. Additionally, you only have to set up the microphones and settings, unlike how you'd have to set up an entire separate device if you used an external recording. Because you don't have to purchase an external recording device, recording directly to the camera is much cheaper than using an audio recorder. The benefits of an external recorder is that it can have higher quality recordings, give more mobility to the sound person, and have more capabilities. As the cables connected to the microphones won't be bound by the camera's position, it allows for more freedom for the microphones' positioning. Separate recorders also tend to have more inputs than cameras, allowing for more microphones to be used to record sound.
