> but in a different world, they could. The issue is margins. That is an additional SKU to manage, and Apple is extremely ruthless in minimizing redundant components, as this was a major reason Apple had horrid margin in the 1990s. All manufacturers are moving away from buttons for that reason - from automotive to consumer electronics. The same money spent on a dedicated SKU for buttons can be spent on a better optimized OLED display to reduce lag.
