I was travel-challenged this week. First, I left my phone adapter at home for my trip to Milwaukee, so my mobile died on day 2. Then, I left my laptop power cord at the client site, which combined with the 30-minute capacity of my Vaio battery left me very unproductive on the flight home. Losing your cell phone and your laptop capabilities in the same day is very humbling; I was instantly antsy at my inability to connect, to log in, to download. I was reduced to a passive state, reading a newspaper and wondering what was happening that I wasn’t aware of. Troubling.
