Even so the difference in price will be justified by the vastly superior hardware of the mini 4 (assuming that the rumors come true).
My point still stands, I would like Apple to offer the option to not include Touch ID for people that do not want it, with the consequent $100 price reduction of course.
Yes, I understand the point but the current pricing with the 2 and 3 is an anomaly and the Touch ID itself doesn't justify the price difference even though it is the only measurable improvement outside of colour.
The same price difference was there between the 1 and 2 and that was a proper upgrade - RAM, CPU, Screen etc.
The plan will be for all devices to feature Touch ID going forward and it would likely cost more to keep different assembly lines to manufacture differing devices purely because of the difference with Touch ID.
