The MBA screen is /alright/. It's better than a lot of Windows machines but you can get better for the price for sure. I'd argue the screens in the Surface line are comparable and arguably better, 3:2, brighter, 120Hz at basically the same price. And there's loads of 4K OLED Windows laptops if you're willing to pay for them.

Apple screens also tend to have pretty bad response times too. They are sharp and color accurate but fall down in places.
