That's an interesting point you mention about not seeing it, because prior to buying an OLED I'd read a bunch about fringing and in many articles I just... couldn't see it. I couldn't tell what was being illustrated in the images.

It wasn't until I sat in front of one for a few hours, in my room and lighting and with my apps and had funny-feeling eyes and a this-seems-off feeling that I decided to investigate. And yes, those macro photos show fringing, but it /is/ hard to understand how the subpixel pattern translates to on-screen weirdness until you've seen it for yourself.
