I received my new 27" iMac late 2012 on Monday, and noticed a dead pixel very soon when I sat on Facebook. It was on the top right corner, so I tried to convince myself that one dead pixel is nothing to worry about. But when you first have noticed it, it's kind of impossible to ignore it, so I called for a replace which I'll get forthcoming Monday. So, meanwhile, I've been thinking: Are chances bigger to get yet a screen with pixel faults or are most of the iMacs pixel perfect? How many of you have received a pixel perfect iMac, and how many have not? Am I a douche for replacing a fine device with only one dead pixel? I paid 2600 USD for it, and that's a lot of money for a student. Therefore I truly want a pixel perfect screen because I do a lot of webdesign, illustrating/working with photos in Photoshop. What are your thoughts?
