At 5am things are very quiet and serene. Nobody is on IM, no one is texting or emailing me. I find myself very focused. I am also aware of the cost of these two hours, which motivates me to be even more to focus and use them efficiently. So far, I have found I am very productive.

The only reason we even consider calling them “mobile devices” is that the iPhone preceded the iPad. If the iPad had come first, we wouldn’t think of the iPhone as a phone; we’d think of it as a tablet small enough to hold up to your ear.
