It’s an integrated information experience for most of life’s activities that runs ever more seamlessly and simply for the user across phones, computers, tablets, TV, loudspeakers, earphones, watches and the internet. It’s secure and private. It incorporates leading edge technologies running in the user’s device, like artificial intelligence and augmented reality. It looks as if cars will be added to the mix.

The iphone will evolve hugely as 5G networks mature. It’s a convenient and practical size for most uses, so I think it will continue to be the most widely used device for a long time.

There’s no comparable competitor in sight at the moment. As Apple owns and steadily advances more of the foundation technologies involved, catching up across the whole spectrum looks like a daunting challenge for a competitor.

I think this is the foundation of Apple’s success, much more than Google’s failure to compete on the quality of Android. It’s a fundamental difference of business models.
