Digital Trends – Imagine, for a minute, that youâre at the airport. Your plane was delayed a few hours, you missed your connecting flight, your phone battery is annoyingly low, and all you want to do is let your loved ones back home know youâll be late while you pass the time watching your favorite TV shows on your laptop or tablet of choice. As you wander into the airport café, your eyes swing left to right like a pendulum. Past the mom with the crying kid, beyond the courteous fellow who feels his bag is more entitled to a seat than you are. You continue to search until you find it, a free power outlet unoccupied by anyone, only it isnât free.
