### Comment:
The S upgrade has always been iterative, though.

### REPLY:
Yeah, but the Xs is missing the big S feature. The 3GS was actually useably fast, the 4S had Siri, the 5S had Touch ID, and the 6s had 3D touch/Live Photos. The Xs doesn’t really have any major selling points over the X or Xr.
