James Kendrick calls laptop users out on their mostly-irrational fear of running out of juice: Cut the Cord—Use That Laptop Without Plugging In.
I have observed mobile workers for years and it is uncommon to see one working on a laptop in a mobile venue without plugging into the nearest available outlet. I have asked hundreds of these workers why they don’t use the laptop unplugged and almost always get the same answer. They are afraid they might be in a situation where there are no power outlets and they want to make sure the battery is full.

My battery lasts about 30 minutes unplugged. It’s pathetic!
