I just spent some time studying the screen. The pixies are noticeable if you look closely at the screen under certain circumstances. Still, if one of my kids complained about something like that, I'd have to thump 'em. I simply can't imagine the circumstances in which the pentile screen would be a problem.
I'm not trying to justify my choice of phones. I knew going in that I'd probably get a Bionic when it comes out as I have another upgrade available. Would I rather have a super Amoled + like the SG SII? Yeah I sure would. Would I trade Motorola build quality for Samsung build quality to get the better screen? No way. I'll never own another Samsung unless they change their build philosophy.
Motorola Droid 3 has world-class build quality and a solid screen. Pentile is neither a selling point nor a detractor in my opinion.
Now the keyboard, on the other hand.... <3
