As someone who hates Apple's facial recognition implementation, I'm eagerly awaiting the day they ditch TouchID for FaceID. That'll be the year for me to upgrade to a high-spec laptop on the last generation with TouchID.
Honest question, why? Sounds like you have a technical issue with it. I’m not a fan of FaceID for digital privacy reasons, but the reliability and ease of use eventually forced me to give in. I don’t think I’ve encountered anyone who hates Apple’s specific implementation of facial recognition.
First is that TouchID is faster and more consistent than FaceID in my experience, but also ergonomics and presence.
With a phone with a fingerprint scanner, I can have it unlocked as I pull it out of my pocket, and I don't have to bury my face in my phone, e.g. to pay. I can unlock it while it's sitting on a desk.
Similarly with the fingerprint scanner on the Macbooks, I don't need to have my face squarely in the center in front of the screen. It's a very bad experience unlocking an iPad Pro with FaceID, but I have no problems experience unlocking an iPad Air with TouchID.
But I think I'm a minority here, so at least I can save some money when the long-rumored FaceID Macbook comes to fruition :D
