New York's flagship Apple Store features a 32-foot-high glass cube that appears to float over its subterranean entrance, with access by elevator or a winding staircase leading to a subterranean tech world. The Apple-obsessed will be happy to know that this location is open 24/7, holidays included. Display walls and tables are lined with iPhones, iPads, Apple Watches, and AirPods, and pretty much any device that the company manufactures or sells. There are often special programs here, so check the website. Make an appointment (well in advance) at the Genius Bar if you need tech help. There also are several more Apple Stores across New York City, including in Grand Central Terminal's Main Concourse and a SoHo location in a converted Beaux-Arts post office building.

Apple's flagship San Francisco store is a two-level, open-air tech temple to Macs, iPads, iPhones, Apple Watches, and the people who use them. Inside, it's more about getting your iPhone fixed at the Genius Grove, but outside everyone is using those phones to take pictures of the modern structure.
