The headset will basically use a WiFi connection, but you want something to try in the store beyond the usual technological demos. AT & T is planning a Game of Thrones experience ( Dead Must Die ) who has donated Magic Leap One to a whale walker. It is a shameless campaign for AT & Ts WarnerMedia, but it can give you a sense of what is possible.
Whether you should buy one is a difficult question. Magic Leap has significantly expanded its App Catalog with everything from NBA basketball to Star Wars but this is still a device for developers and well-known former adopters. It's not meant to be a regular headset, and you might want to keep it off unless you're completely sold on the concept.
