A while back, I tried traveling on business with nothing but the help of three smart phones. I quickly ran into the headroom of those devices and, by the time I was home, I had a huge list of tasks I needed to deal with that could only be done on a computer. I wondered how I would have fared had I carried an iPad with me instead. So over the last two weeks, I’ve done just that, carried an iPad on my travels and left the laptop at home.
