The Macbook SE would make a far bigger impact outside of the US than inside the US.
Apple is known to target margins for high-end devices. Apple is also known to capture market share with SE products. Why is this so hard for you to understand?
You keep saying Apple won't "fight in the trenches". $750 is not in the trenches. $400 is. In addition, Apple Silicon costs 4-5x less than buying Intel i3s in the low end. See my post
here. Apple won't ever have to fight in the trenches because of Apple Silicon.
No it's not. The iPad 10.2 is the iPad SE. Then there's the iPad Air, which is a step up. The $1,000 Macbook Air starting price is still well above the mass market for laptops, especially in developing countries, where a Macbook SE would make the most impact.
