So this guy wrote a piece for Popular Science magazine on how to build a WiFi hotspot backpack. It’s $1000, and yes, while cool (the geek in me is drooling), I wonder if things like The Quiet Zone are in danger. So to all you PR flaks out there, when talking about why you aren’t returning my calls — “Oh, s/he was traveling!” — get over it. There’s no excuse now, bitch.
