actually, I dont mind the banding/pen-tile grid on the Samsung Galaxy Nexus that much.. only happens with a handful of colours and only on very low brightness

From a mobile-display perspective I would much more prefer:
1) improved direct-sunlight performance. N810 was amazing, but so low-res/grainy from digitizer
2) less narrow display, 16:9 is just uncomfortable in *either* orientation .. this is what really bugs me about the Edge
