It was life changing for her.
She watches YouTube mainly; she selects videos of her interest areas using voice (button less remote with Mic). Mainly watches exotic and local travel destinations. Things she has heard of, but never had a chance to go. She particularly likes the intimate, off the beaten track, short solo traveler's videos.
She feels liberated, as she says she is traveling without the need to leave the house (which she cannot due to her age and mobility issues).
Without smart TV this would not have been possible.
