In wishing to ban smartphones, Tim Watson (nearly 94) throws the baby out with the bathwater (Letters, 20 December). Being of a certain age myself, I remember when nobody in my close family even had a landline.
Smartphone use can become misuse but, used intelligently, the smartphone is one of the greatest modern inventions. With mine, I can call people on the other side of the world cheaply or even at no cost; I can use it as a satnav; I do not have to speak to everyone because I can simply send them a text; I can store important information and use any number of apps.
