AT&T’s new flagship, on Chicago's Magnificent Mile, is designed to immerse customers in everything AT&T. The 10,000-sq.-ft. store, at 600 N. Michigan Ave., also offers shoppers a peak into the future, with the first-ever retail demonstrations of the company’s new digital home security and automation services. It also features a connected car (a 2012 Nissan Leaf) that is used to demonstrate how wireless technology can help driving.
