It’s not a computer, it is a swiss army knife. I had no idea until I owned one, but it is the most useful tool I own.
I have an iPhone and an iPad that I carry everywhere with me. What I have found is I no longer need the iPhone. All I need is a simple phone so my daughter is turning my iPhone into an iPod for herself as soon as I get a different phone at the end of this month. My monthly charges will be much less too.
