I've searched Google images to view various MB colors. I wanted to ask anyone here of what they thought of the Blue MB? Is it a dark blue or light blue? It seems that in every picture I view it looks different. I'd prefer a dark blue or even an electric blue, but if it's a light or sky blue, then I'm opting for the gray one. Also I read that there was, or will be, a purple MB offered. True? Thanks.
