They let me open this one at the store, but at that point, considering she did not really she the issue with the Air, I decided just to say I'll look into it at home. I have had the following issues:
(1) Rev A, bought day one, dead pixels in the screen. = Apple replaced it
(2) Rev A, late Feb, 08, Hard Drive deleted itself and had no free space = Apple replaced it.
(3) Rev A, march-april 09:
- Trackpad button scratched the bezel = Apple replaced the bezel
- Trackpad button got stuck in the down position = Apple replaced the button
- Macbook Air came back with a broken and lose hinge = Apple agreed to repair it, but I decided to wait because I needed the machine
- Last week, the Air got a bunch of flickering black lines on the left side of the display
- After 4+ hours both in store and on the phone, Apple agreed to replace the machine with a Rev B
(4) Rev B, last Thursday, had the gray line issue (I thought I was crazy until I looked it up) = Apple replaced it today, although the Genius' did not believe me.
(5) Rev B, present, has the Gray line issue, but it is less than the other one.
At this point I am not sure if I should keep it or just complain until Apple lets me trade it toward a Macbook Pro. I really love the Air for its size, and I don't want the Macbook due to the crappy screen. The 15" pro is really my only alternative. I might just decide to live with the issue, or go to the other Apple Store first in my area and see what they say about it.
For the record, Apple is not going to let you open countless Air's, especially on an issue that goes unnoticed by the Genius Bar. They will go for it once, but that's really it. Considering it seems to affect greater than 75% of the Air's, I have no confidence that if I trade this one in I will get a good one. I am just tired of all the issues I have had with the Air line. It is not ready.
Apple fixed a lot of issues with the Rev B, but this screen problem is ridiculously widespread, its just that many people can't notice it or we're all just crazy.
