Interestingly, a Pentile display should be called "retina" based more than simple high resolution screens should, since it actually takes into account how the retina sees color, with less resolution needed for red, and less green required. For the natural objects that our eyes evolved to look at, Pentile is perfect.
However, for unnatural things like text, Pentile is nowhere as sharp when held at the same distance on the same resolution screen.
It all depends on how much you read at the lowest zoom level, versus working with images.
For me, sunlight readabilty is more important in real usage. At work, we use transflective LCDs for our field apps, and those are perfect in sunlight. I look forward to trying a Super AMOLED.
