For about seven years, Apple has maintained a consistent iPhone product strategy. An entry-level phone (first the SE, now an e) anchors the low-end. The mid-range is represented by a "plain old" iPhone with no modifier (sometimes including a larger but otherwise similar Plus) and a slightly more approachable version of the previous year's mainstream iPhone. The high-end is represented by a Pro, with the extreme high end being the Pro Max. "Extra" products such as the mini and the Air (likely) come and go—but they always sit somewhere in the mid-range.

The introduction of the iPhone Duo—hitting stores this Friday, October 16—throws this product strategy into the proverbial cocked hat. No longer is the most capable iPhone the most expensive. Now, the most expensive iPhone is essentially last year's mainstream iPhone with a special set of displays. The iPhone Pro still has the best cameras (front and rear), the widest range of other sensors, and Face ID (the Duo has Touch ID).

This new product positioning strategy doesn't mean the Duo lacks appeal. In classic Apple fashion, Cupertino has waited until:

• They have confidence in the technology that is new to them (not necessarily other companies)
• They can bring the product to market at a price they believe some of their customers will pay

—it's going to be tough early on to decide whether the Duo is a success. Even without fabrication yield issues and component cost challenges, Apple certainly isn't expecting the Duo to sell like a mainstream smartphone. The real test will be whether early Duo adopters replace their Duo (2026) with a Duo (2028), Duo (2029), or Duo (2030) — assuming, of course, that Apple is still making the Duo.
