The attention lavished on the iPhone is indicative of how important it is -- it still makes up about two-thirds of its revenue. For the most part, Apple spends most of its time with upgrades to its iPhones, last year introducing the edge-to-edge screen and Face ID facial recognition system in the iPhone X, and this year adding it to its entire iPhone lineup. The new features make iPads and Macs look like they're stuck in the past -- and even behind rival products from Windows PC makers.

But iPads and Macs remain a critical part of forming the universe of Apple products that hook a customer into its ecosystem. If you've got an iPhone and Mac, you're less likely to switch phones or computers to another vendor.
