I’m pretty there will be some case of a $750 laptop with a 3K OLED 120Hz display. As I mentioned, there are still many other things to consider if it’s a good display (better than the MBA).
But even then, I’m pretty sure there’s a cheaper laptop than the MBA with a better display. You can put emphasis in one are. However, I’m equally sure that there’s no laptop that checks all boxes (great screen, great performance, great battery…) at the price of a MBA. Unlike in other fields, Apple has a huge advantage here.
