Dude, half the case is covered by foam wrap... that's why it doesn't look centred.
You know, I've read through all 12 pages here and it AMAZES me how many people don't realize that the foam is covering the other half. I saw that immediately, it really isn't that hard to understand.
I, personally, think it is good that they are updating the line with aluminum to match their other products. I am impatiently waiting for a new MB to be introduced with a screen larger than the current one without having to go to the MBP.
