They also sell more insurance to people more worried about breakage. Just like Anker sells more cases.
Not saying the glass isn't more delicate than the aluminium, but there is an incentive here to be a bit one sided. A 6' drop test, for example, is biased toward a result.
Yes there is that but glass is glass. Never bothered w/ AC before... typically do break my screen once every couple of years. In the past that meant $99 or $129 for an official repair. Much less than AC cost + $29 repair. But a mostly glass exterior + Apple’s new repair cost prices makes AC or other insurance not a terrible idea for the 8 or X. Not sure if I’ll go that route or just a ruggedized case. Those are so bulky and heavy though. Kinda ruins the experience. So no matter how ridiculous those tests might seem they make a point. I’ve had some crazy falls when running so I can see some of those tests being realistic.
