Beg to differ, there was/is a major issue on the 2007 iMacs both 20 and 24" models in that the screens have gradient differentials that have been widely reported and are well known. It shouldn't bother a normal "mac life" user. You probably wouldn't notice it if you are watching movies, surfing, spread sheets or the family pics, etc.
If you are a serious photographer or any serious content creator using image editing programs and concerned about color correction, its a <snort> no pun intended, glaring problem. The hope is that the brand new iMacs will have solved this problem. We shall see.
