I tried to place an order for a 64GB gold 5s online, but ship dates went to October almost instantly (tried online at exactly 3am EST, in Canada).
After seeing the gold demo model at an Apple store, I am SO GLAD I didn't end up getting it. Space Grey is a lot nicer in person and that's the model I'll likely be getting when they're back in stock around these parts.
I was quite surprised as the gold one easily looked like the nicest one in all the press photos and videos, but in person, not at all.
