I've become accustomed to white Apple devices (had a white 4S, have a white iPad) so naturally I was disappointed when I learned that gold and silver were not in supply at the Apple Store.
Well I stood there on launch day since 3 AM and I wasn't about to walk away without an iPhone 5s, so I just "settled" for the Space Grey.
I put "settled" in quotes because even as I was planning to visit every Apple and AT&T Store on my drive home (I go to university), I just noticed how the phone shines. The reflections off of the chamfers are not as subdued as they were on the 5, and they give off a spectacular, but not blinding, glint all around the phone even in only partly sunny weather.
You just sorta get that feeling that you're holding an Apple product in your hand, the feeling that there is no compromising on any aspect of quality or detail regardless of the product and configuration you got. This was not "settling." This was buying a spectacular device all-around.
I also like how the aluminum is a lighter color, as the 5's Slate was too dark for my taste.
I abandoned the idea of crusading through all the stores looking for a white model. I'm happy with it, and it will be the phone I will use for the next 2 years.
