Earlier this year, my XS hit the ground at the exact angle where the bezel ends and the screen starts on the bottom lip, uncovered by the leather case. No cracks, but it caused about 1/4 of my screen to die, which warranted a full display replacement ($$$) in Apple’s eyes—although several people I spoke to diagnosed it as most likely being a dislodged display connector and nothing more. (I never went through with the repair on account of stubbornness.)
This long-winded story is to say that I rejoiced when I saw that the leather cases cover the bottom lip this year.
