AppleInsider:

While the new 27-inch iMac does not feature the much-awaited redesign, and it does feature chiefly minor specification improvements, it’s also got one big extra. Previously, to get Apple’s high-quality nano-texture glass on a Mac display you had to pay $5,999 for the top-range Pro Display XDR.

Rather than diffusing reflections on the glass or perhaps trying to compensate for them with greater brightness, Apple cuts fine lines into the display. This means the monitor does not present a single plane for ambient light to bounce back from.

This is a big deal to those of us who hate reflections but can’t afford the $6,000 Pro Display.
