On Wednesday, Apple introduced not one but three new phone models to the world: the iPhone Xs, Xs Max, and Xr. They all seem fine. But take note of what Apple took away. As of this week, it no longer sells the iPhone SE. Which in turn means the age of small smartphones has officially come to an end. When Apple debuted the iPhone SE in 2016, it was remarkable not just for its diminutive 4-inch screen size, but for its amped-up capabilities even given those constraints.
