I like my wii white thaks. White just looks nice and clean.
As for the colours, I would probably go the silver or black if I had to. But from all the pictures I have seen, the base does not match the console, I think if they made the colours match (yeas I am aware they don't match on the wite original one, but you can accept the difference on that one because it is the original) I think they would be onto a winner.
