I agree. I think the white makes it look pristine, elegant and classy. But a phone can also get dirty very quickly and it would be really hard to keep it looking as good as new.
I think that while the white colour would look good on the S4, it might also look a bit cheap, kind of like a toy, and as they say "Black is the new white". Black is also elegant, I think.
So I'm torn between the two! But most probably, I'll get a white S4 but to make it look less cheap, I'll get a premium-looking white cover on it.
I typically like white phones although I have a grey Note 2, so if I were to get this phone it'd probably be in white. Although the "black" version does looks ok.
That's not really black, more of a dark grey. But I suppose if it were truly black you wouldn't be able to see the design so I guess it's good enough. One good thing though is that the phone in real life doesn't look like it has a dark blue tint like it has in the promo pictures for some reason.
EDIT: Damn, on second thought the design on the black version looks really nice. Hmmm.
I would go with the white model. I've had nothing but black slabs as phones for the past few years, and having used a white GS3 for a short few months, I enjoyed the look of it.
initially was decided on the white. but after shopping around and reading the forums ( and especially seeing the spigen neo hybrid cases) i have a feeling i'm going to be a getting a black one
