I've already made a thread a week ago asking about specific issues for a specific model, but I'll make this one more obvious with the title and its scope larger.
It seems like the majority of issues we can read about are related to the 27", with only some people mentioning having problems with the smaller model.
The idea is if you have any problem with the 21.5" and only the 21.5", regardless of the graphics card, manifest yourself in this thread so we can see how this model is affected compared to the 27" ! Yellow tinge, flickering, noisy screen or HD, you name it..
