I know people just bought an iPhone X and would like Face ID to improve, but in-display fingerprint scanner just sounds better.
My phones are usually either next to me or charging. If I hear a notification, I would like to unlock the phone in the dark while my eyes are still closed and before I even raise the phone to my face.
Think of Schiller saying iPad Pro replacing a Mac. That's asinine. It's a mobile OS vs desktop. A keyboard of a Mac is still superior to an added keyboard of an iPad. Easier to touch type (blind type).
I would prefer unlocking my phone without looking. It's laying on the table and it is already unlocked before I pick it up. Samsung gets first dibs while still keeping its iris scanner which works pretty well already.
The iPhone X is about compromise over choice. Buyer's remorse will start to boil within a year or so if it's not happening now. Same thing happened to Galaxy S6 edge and Note5 in 2015. Lacked IP rating, microSD slot, and removable battery. Two out of three came back by 2016.
