Apple streaming event: Why the products announced today could be more important than any new iPhone

Apple is about to take to the stage in California and unveil its latest product. But there will be no moment where a laptop is pulled from an envelope or a phone from a pocket.

Instead, its newest announcements will be a series of services: subscription platforms that allow people to sign up to watch TV and films, read the news, and play games. We'll tell you what's true. You can form your own view.
