Apple has done it again. The $3,500 Vision Pro headset takes all the major computing trends of the past two decades, places them around your eyes in a way that looks sleek and feels comfortable, and offers an intuitive interface that is novel and intimate.

Following Apple’s two-hour presentation on Monday, I was among the first people to receive a private, 30-minute demo of the Vision Pro and had a chance to try a variety of features — including one “killer app” not mentioned in chief executive Tim Cook’s keynote address watched by millions online.

Moving from app to app using the device could hardly be more intuitive thanks to eye- and hand-tracking. Click a button with your right hand, and an iPhone-like home screen appears. Glance at a photo or icon, then pinch your fingers to “double-click”. You can scroll through photos with a swiping gesture, or zoom in as if a giant smartphone were projected in front of your face.
