Shadyside’s Walnut Street is home to the only Apple Store inside Pittsburgh city limits. It has the usual chrome shell and blueberry employees filling the interior with a relaxed sort of bustle. You can count on a steady sprinkle of curious Apple-seedlings entering the store, and a dozen azure employees rotating on and off shift. For guests unattuned to the electronic giant’s latest activities, you can always estimate the imminent release of a new Apple gadget by the length of the line that stretches down Walnut Street.

If you see a conga line populated by design school graduates aggravating Shadyside’s otherwise sedate drivers, expect a new iPhone soon.
