In years past, tech fans and industry commentators alike would mock Apple when it came time for the launch of its interstitial S model iPhones, noting a lack of substantial change between, say, the iPhone X and iPhone Xs as compared to the wider rift between the iPhone X and iPhone 11.
Fast forward a few years, and Apple has ditched the S suffix altogether, instead marketing each year's iPhone as a full-on numbered release. The iPhone 15 is followed by the iPhone 16 and so on.
