I know this borders on sacrilege to say on HN, but I enjoy going out and camping in places where there is no coverage. Being utterly alone sometimes is nice...... I can see the stars (well, I live in Washington, so I have to travel a bit to camp where I can see the stars, but... you know). I, personally, would mourn a little if 4G reached everywhere.
I get that, I too enjoying switching off and doing nothing. It's when you need it for an emergency... that's when you realise how poor the global coverage is.
