It's funny how this depends on eyes for different people.

I have a co-worker who cannot look into pentile dispalys, he says that the colour fringing makes his eyes hurt.

Myself, I honestly cannot make difference with pentile ot lcd display, in my eye N9 looks nice, it's bright and easy to read.

I do not know if the difference is physiological or psychovisual, but it is real. People are different...
