It’s a random Friday morning. I wake up ready to work and the radio on my AirPort stops working. I reset the device, do everything I know to do, but there is no SSID, no radio signal whatsoever. What to do? String a cable across the room so that it can get ripped out of a computer when the crazed, six year old invariably streaks through the office having watched Power Rangers and looking to chop me into pieces? Not a chance. I’ll just run out to the closest Apple store and grab a quick replacement. So I hop in the car and drive to the mall. What is going on…
