I have to be honest, I never understood the idea of pushing higher and higher resolutions on such small screens.
Especially for gaming, where there's lots of motion, but, even with cellphones, it just seems like doing it for "bigger numbers." My old LG Optimus L9, with its 960x540 resolution, managed to be quite sharp. Yeah, the screen was only 4.7 inches, I get that. But I don't think a 7 inch screen even needs 1920x1080. I'd say the 1280 resolution (by 720 or 800) is a really high pixel density.
Nobody complains about "gigantic, blocky, Atari-2600-type resolution" on a 24 inch monitor that's 1920x1080, after all.
