> When the pixel density of your screen is high enough, sub-pixel rendering stops making sense I wonder if the prevalence of Retina displays across the Apple product line coupled with the prevalence of rotatable displays from iOS devices made them go towards something consistent across the board: because 90deg rotations really doesn't play well with subpixel rendering, doubled down by having to handle four different orientations with a single font and have it display consistently on a single device, it makes sense to go with simplicity and walk the antialiasing route, and since you have Retina basically everywhere, well, just flick the switch everywhere as well. I seem to recall (years ago, so memory may fail me) some blog post explaining how dropping subpixel rendering also allowed for some major cleanup in the Cocoa/CoreSomething rendering code.
