Indeed it should be interesting to see if gold is as hot this year, since it's not the new kid on the block anymore as it was last year.
Part of my reason for declining the gold was that it looks really putrid in the wrong lighting (like when it looks ugly brown). Yet it really is gorgeous when its a glistening hue of gold (such as in sunny daylight).
I was really on the fence at launch, but for me it is best that I stuck with my first instinct of silver.
And as an aside: I came from having all black on previous iPhones, and enjoying that the black screen on black bezel made the screen feel more organic and larger. But I wanted change, and am highly satisfied with the white bezel, and probably will get another silver/white next year when I'm due for upgrade.
