Go big or go cheap? That is the existential iPhone question Apple may tackle in 2018.

The company plans to introduce three new iPhone models later this year which may include a considerably larger version of the iPhone X -- the iPhone X Plus, perhaps -- as well as a significantly less expensive version. It's worth noting that price hasn't been a major obstacle for the premium flagship so far; though it's the priciest iPhone ever at $999, £999 or AU$1,579, the iPhone X was the best-selling phone for the first three months of 2018, followed by the iPhone 8 and 8 Plus. Of course, a less expensive version would almost certainly broaden its addressable market. Six plus months after the iPhone X's release, however, the phone has lost a bit of its initial sheen.
