It is a 3-piece magnesium, so I am speculating this may appear in different color sometime in the future.The Surface 2 is unibody and then the kickstand. So it isn't interchangeable. It does look like it only comes in "white" but I think in normal lighting it won't be as loud. Most of the pictures I've seen have had it blasted with light.
Interesting comment about the Surface logo being garish. I would never argue someone's taste, but does anyone else feel the same way? I think it looks very nice. Also, I agree with the opinion above about replacing the Windows logo. Good move.
