I just got the nano textured glass on my new M5 13” iPad Pro this week. The benefits of reduced reflections are major. My condo is quite bright and I’m always near a window and I have no problem reading the screen. I don’t think that fingerprints are worse, if anything they are reduced with the nano textured glass. I also feel that touching the screen and scrolling or writing with the pen feel better than the glossy screen. Your finger or the pencil slide better on this screen. Those are the positives so far of the nano textured glass.
The negatives are that yes, the blacks are less inky than my iPhone’s OLED screen. I also feel that tiny fonts are just a tiny bit less sharp. Colours are slightly less saturated.
