Do you want to install it? Let's talk about that. > Many of the updates are cosmetic or just reworking of already existing capabilities to make them faster and easier to use. That's not to say they're unimportant -- turning something that's a real pain to do into a somewhat lesser pain is always welcome. There are also some completely new features, but the best ones, such as Continuity Camera and group FaceTime, require an iPhone running iOS 12, also in beta.
