I just received my 24" iMac and it only ha one problem that I can tell. The backlight gets dim on both the right and left sides of the LCD. Does anyone else have a similar problem on the 24" iMacs? If so, has anyone talked to Apple about and if so, what did they say? This is not something I am terribly concerned about. Unless I have a solid color desktop or image across the entire screen, I can't really notice it. But when the computer boots up, it is quite obvious.
