My sons run the world using their phones

Mine is generally in my bag. It's there if I need to phone home to let HWMBLT know a)where I am, b) that I'm going to be late, or c) that the car has broken down and I've phoned the rescue folks.
It's a useful tool; it's your own fault if you let it rule because it can only do what you let it do.
Mine's like John's by the sound of it

I am firmly in the KISS camp, but the ones the Sons carry are like something out of science fiction. The world moves along, and my son can literally phone me from the other side of the world as easily as he does from his flat in town.
My 93 year old Uncle uses his all the time; he keeps it on and charged and it's a boon and a blessing of a thing for him. From the, "I need a lift home", type call, to the making appointments and phoning home to say he'll be late

it's in daily use.
He runs up a heck of a bill blethering to his 95 year old pal down in Ayr though !
Do I take mine when camping ? usually, but it's usually off, and I try and mind to check it once a day to keep everybody happy at home
