“If you look at the cost differences between the non-Touch Bar MacBook Pro and the Touch Bar versions, there seems to be about a $200 price difference for roughly equivalent models,” Chuq Von Rospach blogs for Chuqui.com. “For the sake of simplifying the discussion, let’s set the price for this system to be $200.”

“That’s not the cost of the Touch Bar, however. That entire subsystem breaks down roughly into three pieces: The Secure Enclave unit, the TouchID sensor, and the Touch Bar itself. From the looks of it, most of the cost is in the Secure Enclave system itself,” Von Rospach writes. “Give that cost breakdown, we can make some assumptions. If we assume that Apple is committed to using the Secure Enclave in Macs to enable user authentication and to secure Apple Pay, I think it’s okay to assume Apple will be including it in most, if not all, future Macs. If that’s true, then the economics of the Touch Bar are minimal.”

“If I’m right, future Macs will use the infrared facial recognition, and they can embed those sensors in the bezel of the monitor on both the iMac and the laptops. This simplifies the problem of needing to secure the communication between the sensor and the Secure Enclave; by moving those sensors into the device and off the keyboard, everything gets a lot cleaner,” Von Rospach writes. “And they can build a much less expensive keyboard with a Touch Bar on it that doesn’t require the level of communication security that would be required if it also had the TouchID sensor.”
