--- but not all worlds. The thing we call a phone is more than that, in fact the "phone part" is kinda minor.
If I still worked in Charlotte, would have the best one $$ could buy and would use it constantly. I am retired and a hermit in Oconee. There is no signal at my home. My T-mobile plan is $2.50 a month and pay as I go. It connects to my WiFi and works well. I seldom have use it, most times don't know where it is. I do take it fishing as it has a good camera.
Phones are now more a mobile computer. As I am usually home, prefer the large screen of a monitor or my big TV. Skype is cheap, but have no one to call. From what I gather folks don't talk much these days (it is a phone), but instead text. I rather use a computer and a keyboard with my fat fingers.
In the world of normal folks, if phones are not in one's reach they feel lost. It has become a very important tool. It is kinda odd to me that even at a Tiger game, many folks spend more time on the phone than watching the game.
I just use my cell phone as an alarm clock. Without good 4g service, it is not possible for it to keep the exact time, which means I could be awoken several seconds late depending on the model of the phone.
