I don't understand people who say this. My friends have pentile phones, and say they don't notice, but I looked at a GSIII, and it was immediately obvious to me. The screen looks sort of grainy, and the colors are all weird.
I prefer Android, so I've been holding out for a high-end one with a great camera and a non-pentile screen. If there isn't one this year, I might have to switch :(.
The color issue doesn't have much to do with pentile, that's why. Yes colors are interleaved, so it sounds like it would be logical - but that's not the case
The SAMOLEDs from Samsung have weird colors because some colors get used faster and their intensity diminushes over time.
On the S3 and S2 (which has NO pentile, still has weird colors) you can mitigate it in the color profile settings
On the S1 there are tools to completely fix the colors, yet it's a low rez pentile display. While you can see the pentile matrix on this one, specially well if close, you can't see the color difference once calibrated. There's just no way.
There's no "grainy" effect that I can see tho. The resolution's just too high to see it at normal distance (on the S3 that is. Definitely something you can see on the S1.)
