The iPhone XS proves one thing definitively: that the iPhone X was probably one of the most ambitious product bets of all time.

When Apple told me in 2017 that they put aside plans for the iterative upgrade that they were going to ship and went all in on the iPhone X because they thought they could jump ahead a year, they were not blustering. That the iPhone XS feels, at least on the surface, like one of Apple’s most “S” models ever is a testament to how aggressive the iPhone X timeline was.
