Using it at its native 2880x1800 resolution would be great though. Possibly hard to read, but I'd love to see it.
Scaling to 800x600 on a 1024x768 screen looks awful. I'm not sure that scaling a 2880x1800 screen to 1920x1080 is going be distinguishable from native resolution for anyone with eyes more than 15 years old.
It would be native, it'd be 1:1.
No, there are 2880x1800 pixels. If you want to use the full screen to show 1920x1080, you are non-native and the math doesn't even out since there aren't half pixels. Now if they had gone 3840x2160...
