As I make my rounds at my IT support job, a common sight emerges: big smartphones with spider-web cracked screens. You don't need to be a structural materials engineer to know that the bigger and thinner a smartphone is, the thinner and more fragile the screen. Add in the cumulative effects of pressing hard on a pseudo pressure-sensitive screen and you've already doomed the screen to an early demise. A common occurrence is the big phone in a guy's front pants pocket that turns 90 degrees (landscape orientation) and bends just enough across the leg to crack the screen when the dude sits down. Time to buy a new one!
Seems Apple knows that because their current lineup drops the iPhone SE and nearly bridges the gap between iPhone and iPad with the iPhone XS Max. The iPhone 7 is currently the smallest and most pocketable but it's so thin and slippery to hold like all iPhones that it, too, seems engineered for multiple replacements. Yes, a case makes it easier to hold but does nothing to strengthen the screen.
Reaction on the web ranges from "Apple can't be THAT dumb" to "Don't be surprised if they're already planning a triumphant return".
Time will tell. Keeping my iPhone SE until it no longer gets iOS updates.
