One more nice thing that some computers do is automatically adjusting brightness depending on your ambient light. Like phones which have dedicated light sensor. But at least my computer uses webcam (or sensor near a webcam) to determine ambient brightness and adjust monitor brightness. EDIT. ah, yes, and i don't use external monitor. But makes me think, why monitor manufacturers have not added that one light sensor to their products.
