I too want to give some balance to this post, here are my purchases for my personal and business use over the last 2 years.
2x 1st gen iphones - perfect
2x 3g iphones perfect (I can personally account for 3 other ppl I know personally that got perfect ones also)
3x 2.4 17' Macbook Pro's - 2 were perfect, 1 had uneven lid that they happily changed for me without any questions.
1x 2.2 15' Macbook Pro - Perfect after a reformat
1 Current model 24' iMac - Absolute perfect.
Over 5 ipods (some as gifts, some personal over the last 3-4 years) - perfect
2x Base stations - perfect
I am just as picky as the OP. Next to taking a magnifying glass to the screen and counting pixels, you don't get find people as picky as I am. To make a long story short, when I had the uneven lid on my macbook pro, I was so mad that they would sell me a 3000 dollar laptop with any defects that I went into the apple store with the intent of being a jerk, but the ppl at the apple store were so nice I couldnt get upset.
I dont doubt the OP is having issues, but
. I do feel like they are probably pretty rare. This board is riddled with people that have had issues, but the few thousand (if even that) people that have had issues are a small percentage of the overall apple sales. Personally, I really want to see this gradient problem first hand. Every apple store, bestbuy, mac store I go to, I end up standing there staring at the screen because I want to know this gradient issue that people keep complaining about. I can kind of see it on the pictures people post, but pictures of lcd screens will never do justice to it.
