Got my wife an iPhone 7 recently.
It's a big step from an iPhone 4S. She uses more data than I do. So, using LTE vs 3G is just great!

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
-- Isaac Asimov
