I don't need a lot of video muscle which is why I went with another 20". I had been working on an iMac G5 for years with no screen issues until 11 capacitors bloated and/or leaked and it died. I expected the newer model to be better, instead it's a dramatic step backwards as far as screen reliability. I may be more color aware than the average consumer, but I'm not a high-end photo retoucher either. Still I can not see any way they consider this amount of gradation within acceptable range for any application. Unless I just have ridiculously poor karma and happened to get 2 bad displays in a row.
