Just got the brand new iMac 27' from Amazon yesterday, while I found there is yellow tint on the lower side of the display which make me unhappy. I took it to genius bar today and they told me they can't just replace it because it was not purchased from Apple. (where will cost me $200 more include tax) The only thing they can do is swapping the LCD panel. Then I have to put the brand new iMac in Apple Store for repair. Should I return it to Amazon instead ?
