Let me say that I'm not a fan of the new Face ID. I like unlocking my phone while it is in my pocket and when I take it out, I'm already on home screen. The process will be slower now. But, there are some advantages of Face ID which I can think of from my daily routine: Can't use Touch ID when my hands are wet. Just doesn't work, period. So when I'm in the kitchen, or swimming etc, I revert to passcode. Can't use Touch ID when the phone is in my bike holder since you put the phone in a cover first. With Face ID I can unlock my phone when riding my bike. And finally, I can unlock with gloves now. The only question is, does Face ID work with sunglasses? If it does, I can't think of any occasion where it will not work from my daily routine. So, it'll be a slower "process" to unlock, but it'll work in more scenarios.
