My iPhone Goes on Vacation

Whil e I use my iPhone every day, I don't usually get to test what it is like to depend on it for an extended time, without access to the technological "comforts" of home. I got that chance earlier this month when I went on a two-week trip that took me to North Carolina and Michigan. I brought my MacBook Pro along as well. But, as a test of the power of the iPhone, I kept my use of the laptop to an absolute minimum, depending exclusively on the iPhone as much as possible.
