Advice to the OP. Stop reading Macrumors, you returned 3 perfectly good laptops that you were pleased with before you read these forums.
When the rev 2 machines come out you will not buy one because they didn't fix the "glaring quality issues" and "Apple does not listen to it's customers" and whatever whining crap the majority of the people out here complain about.
Your problem is not that your computer had the issues you described.
Your problem is that you read Macrumors, discover the "issues" that other people out here complain about, realize that your computer has them too and get upset.
I fell into the same boat as you, suffered from product dissatisfaction for awhile, then one day stopped reading Macrumors and learned to love my 2nd Gen MBP.
There are some wonderfully helpful posters here, and if you have a genuine problem, you may get lucky and they will actually help you. The vast majority are the ones who have a love/hate relationship with their consumer behavior and will never be satisfied. They are tainting the forums with their complaining and wikiwhining habits.
Next time you buy an apple product, stay off the forums and learn to be happy with your own perceptions not influenced by the dissatisfaction of others.
