Seems like Space gray in 32 GB is the hot ticket but it hasto be your call, Go take a look at them at one of your big box stores if you have one near you and you will make up your mind quickly. Thank you for the question. Hope to see you as a new member.
The gold is a totally different beast in person. I was all for it, but ended up with a space gray one. I finally got around to visiting an Apple store this weekend, and I must say, not what I expected.
Space gray, so much neater and more... neutral. The gold also seems to dim itself with the light, so I don't know if that factors into your decision or not.
