So after 3 swaps on my 27" iMac I had them open one up for me in the store to inspect. It was awkward to say the least and I wondered how anal I was being, so after staring at a bright white screen for a few minutes I decided it was probably ok and took it home. I mean what are the odds of so many of Apple's new "ultimate display" having so many problems. I was told that it would be my last exchange by the Apple Store manager so I was nervous to say the least. I got home and instantly saw a dead pixel, it was not as bad as the other issues I had so I decided to embrace my new little buddy. I just wanted to say the I LOVE the whole Mac experience but every now and then I get extremely disappointed that I was unable to get a perfect display on my new $2000 dollar investment. I love you Apple but come on!!
