I wanted the blue, but they didn't have it in 128gb when I stopped by the Apple Store, so I got the Gold. It was always between those 2 colors anyway. I like the space grey...but wish it had a white front. As a photographer, I don't like the black front. It's too reflective in sunlight, and at night, the borders bleed into the frame so that I don't know where the border ends and the picture begins.
The gold is very more muted & understated than I thought. Very classy looking. My iPod touch looks like an iPhone now. Heh heh heh.
But truth be told, I keep a rubber case over my iPT anyway, so it doesn't really matter what color it is. I dropped my iPT5 and the screen cracked.
