The Taptic Engine existed because they decided to do away with the mechanical home button, ostensibly for "waterproofing." The decision to retain tactility led to necessity for a larger more precise vibration motor, and then punting the headphone jack out of the phone became the obvious thing to do, with a bunch of post-rationalization externally and internal justification hinged around accessory sales.

- eridius 8y agoAIUI the home button was by far the least reliable component left on the phone and the biggest driver of AppleCare support for non-accidental damage. The problem was so bad that it became an Asian cultural thing to turn on the accessibility feature that gave you an on-screen home button control and to use that exclusively, literally never touching your real home button, because you needed the real home button to remain intact for when you wanted to sell your phone later.
- yellowapple 8y agoAnother option would've been to remove the physical button entirely, which is exactly what happened with the iPhone X (I think? I've never used one; only seen pictures) and with pretty much every flagship (and even less-than-flagship) Android phone nowadays.
