4S doesn't have LTE, and Siri is very debatable as requiring the new hardware, so that one was a pretty weak update.

  As it is, 4S was developed under Jobs.

    No, it really wasn't. Did he have some idea the 4S was the direction it would take? Sure. But for God's sake, that phone was released a week and a half after he died. He hadn't been at work very much for a year before that.
