Ask What Led To

How did Apple’s iPhone lineup become split between budget, Pro and foldable models?

The answer, in one paragraph

Apple expanded the iPhone in stages: it turned the original touch-screen device into a software and connectivity platform, added choices in screen size and price, then established a $999 flagship benchmark alongside lower-priced models. The iPhone 11 made the Pro distinction explicit while retaining a $699 entry model, the iPhone 12 showed that a generation could span four variants, and the $599 16e replaced the SE as the value branch. Apple then added the ultra-thin Air, raised the iPhone 18 Pro price by $100, and introduced the $1,999 iPhone Duo foldable. The September 2026 event made that segmentation especially clear by announcing Pro models and Duo without a standard iPhone 18.

The argument runs in 4 strands, in the order the answer makes them, not by date; inside a strand the steps run forward in time, and a closing section lists what pushes against the answer. Each step is a dated entry with its source.
