Hi Everyone. Last week I bought a brand new iMac 27" 17 3.4ghz the same day they were released here in Japan. It was a lot heavier than I imagined it would be, so I struggled all the way home with it on the trains. I got it out, turned it on, and proceeded to install all my stuff. It wasn't until I changed the wallpaper to a solid color that I noticed a slight discoloration at the bottom of the screen. Starting about 2cm from the bottom, and about 3cm thick, was a patch of slightly darker screen which ran right along to the other side of the screen. To begin with I tried to ignore it (not wanting to believe that my iMac wasn't perfect. Today I took it back into the Apple Store to get it replaced. I showed them what was wrong with it, and they went to get me a new one. While they were gone I checked all their display models - they were both perfect. They put the swap through the computer before opening the box (I thought that was stupid), only to find that it also had a distinct line along the bottom of the screen - although not as bad as the one I returned. I pointed it out, but was told it would have to be sent for repair/to get looked at. I resisted, saying that I hadn't even left the store, why would they send it for repair. They got a second iMac out and set that up next to the 1st one. It too had the line along the bottom of the screen. The Apple Store employees said "We can't just take them all out of their boxes. You can choose one of these two, send one for repair, or get your money back". I chose the second one - the lesser evil. It isn't that obvious if you don't know what you are looking for - but it isn't perfect. For that sort of money I expected a perfect screen! As for not being able to take them all out of the boxes? They shouldn't be selling them anyway! Of course they should take them all out. Why have Apple not sorted this problem out?? They've had these issues for years!! I'm sad to say that my opinion of Apple has dropped a little after this.
