Gaming: With advancements in Metal and Apple silicon, Apple devices are becoming a unified gaming platform capable of running console-class games.
OS Updates: The latest OS releases include numerous new features, with Vision Pro taking spatial computing to a new level. Over 1000 apps were available on the App Store shortly after VisionOS's release.
