Sorry but I don't know how anyone could come to that conclusion... the 360 looking better than the PS3? I've always thought that the poor design of the 360 was because it was rushed in order to get it out and selling consoles quicker than the other companies. Apart from the PS3 being curved, it's a very slick looking piece of technology. The 360 in its matt plastic case and having an obtrusive hard drive really does look quite old and dreary.
And yeah, the N64 is grey. No doubt about it. Nintendo are wrong if they call it black, since it isn't.
TV, black; 360 elite, black; PS3, black; Wii, white.
Wii is the only thing that clashes for me, but it looks good so it doesn't bother me.
