Some sorry souls also see pink/green flickering on plasma screens LOL I'm glad I'm not one of them

Pentile is cool. It's much better than people give it credit for. The 3.9 inch screen on the N9 is actually has almost as high PPI as the SGSIII screen.

Another thing. A 480 x 800 RGB has 480 x 800 addressable pixels (each full RGB pixel). A 480 x 800 pentile has 960 x 800 addressable pixels (each sub pixel). Even though a pentile screen has lower sub pixel count and thus lower "real" PPI, this is offset to a large degree by adaptive sub pixel rendering.

As screen technology becomes cheaper and PPI count higher, everything will be pentile (or similar) in the end due to reduced production cost.
