This is just more change for the sake of change because they really have no other actual objective improvement to make to the device.
I understand they claimed they needed room for internal components when they removed things like the button and headphone jack, but after having partially disassembled my own phone for DIY battery replacement the power and volume buttons are so minimal in volume that there can’t be any measurable gain for the consumer by removing them. The only potential gain is a reduction in manufacturing complexity and a cost savings for Apple. Personally I think this was the case for both jack and button as well. It wasn’t about internal space as much as it was eliminating components to save costs.
Personally, I miss the tactile button that confirmed a press and executed a function when that button was pressed rather than swiping up and hoping it catches the gesture right to switch apps or close them. Especially to get rid of the phone search window. Anyway, I don’t mean to be the guy that gripes about change, but IMO these changes are about profits and not the user, they remove valid and useful functionality.
