I'm really surprised that it works as well as it does, given the insane amount of stuff that it interacts with. I'd think that it'd be way more fragile than it is.

I'll also add that while I very much prefer dark mode interfaces -- staring at a light mode interface in the dark is kind of like staring into a headlamp -- if I had a display that (a) was reflective rather than transmissive in the sun (like eink displays are) and (b) did reasonable automatic brightness adjustment, and (c) software consistently made use of a color range such that "standard light background" isn't "set every pixel on the display to its maximum brightness", I might be okay with light mode. If I had to pick just one, I'd choose dark mode, but if technology advances, I might be okay with light mode.
