I received my MacBook a week ago, and the machine is a joy. It has been perfect in every way except one: the backlight seems a little uneven. There is a very slight gradient from dark to light as you look from the top to the bottom of the screen. The gradient is almost prefectly even, transitioning almost as if it was intentional. From reading posts on various forums, I've found out that the backlight should be even across the screen when viewed correctly. My question is, is a little slight gradient in brightness across the screen normal or not? I've never owned a laptop, LCD, or plasma screen in my life, so this is my first time looking at one. If it is not normal, should I just take the MacBook to the Apple store down the street to get it fixed? Do they normally take the computer, leaving you without one? If they replace your computer will they at least swap the hard drives out? I don't have a backup of anything on this machine, and I've already ditched my old machine (it was on its last leg). I really do like my MacBook a lot. It's my first Mac and my first laptop. It's totally quiet, and problem free sans this little issue.
