Hi... I just bought the Macbook Air 13" and I have a question about the colour profile of the display. I'm migrating from a mid-2008 Macbook pro. The Macbook Pro has more of a bluish colour profile while the Macbook Air, I've noticed, is a lot more grey. When I boot up the Macbook Air, the bootup screen is light blue initially and then it changes to grey. Is all of this normal? Thanks.
