I also finally got a chance to stop by the Apple store yesterday to check out the gold color in person, just to see what all the hype is about. To me, the gold looks okay in pictures, and I'm glad it's more of a champagne than bling bling gold. Bling bling gold would have been hideous.
In person, the space grey was boring. Looked like it look a step back and went back to what the black 4/4s looked like.
I think the gold looked better in person than what I've seen in the pictures. The gold was very subtle, almost too subtle. The gold ring around the home button just bugs me.
At the end, I'm glad I went with the silver. I had the black 4 and 5, and was definitely ready for a change in color. Some might say the silver is no different from the white 5, but to me, I think that's the best color.
