Thanks for all your comments, however you seem to miss the point that a warning system is a last ditch effort by the airplane to stop the pilot hurting it. I agree with verbal, memorised and checks built into the flow. A warning system is definitely NOT something to tell you when to put the gear down. However, the single pilot, non bus driver, can be presented with unforeseen situations that lead to distraction (usually multiple) at the critical moments. A backup for when you are human is good.
