You know, I feel dumb now that you're pointing this out. I'm not sure why I originally interpreted this value as an "amount of identifiablity" variable rather than the pure amount. You're right to point that this is a variable that can only be used in support of others and not unique in of itself.

I would think this would make it more likely to be less common. Apple has tight control and thus more consistency. But it is a good point, especially considering the prior point. The M2 Air has a different screen size than the M1 Air, which has a different screen size from *-Air which has a different from pros and so on. We don't need to get into UI scaling to change that. I was just thinking about consistency and popularity of the Apple ecosystem, in the West, compared to the variance in Windows machines. For example, I know that canvas fingerprints tend to have lower variance between apple machines of the same model than windows/linux machines of the same model. Just because there is different chip binning. I was thinking about the same thing with screens. But again, I clearly did a major brain fart and I appreciate the correction.
