the matte display drastically diminishes contrast and color saturation compared to a glossy screen like an iPad mini or iPhone 14 pro. unfortunately there's no option to get a glossy inner screen, because of that dang crease.
the good: the displays are a lot brighter. very readable in the shaded sun of the apple store. (i wasn't able to get any direct sunlight, so difficult to say if it's as good for that as an e-ink display.) looking forward to the oled iPad mini.
verdict: not worth $2000.
