I'm lucky enough to get to look at both every day as I have a black XS and my girlfriend has a white XS.
They both have their positives - The black looks a bit classier overall in my opinion, but the white makes more of an impact when you pull it out. It does tend to show dirt easier but I've found that it comes off just as easily and looks new in no time.
The main positive about us both having an XS is that I have two phones to test with
I prefer black, but I'd ultimately prefer a white one because I like the bottom signal thingy white and most of the fronts black
But I noticed something! My friend got the black xps ( I decided to get white btw) and the back cover and the sides much smoother! Maybe it's partially due to the anti scratch and smudge or whatever the white one has.
Also, what is that smell I smell when I open the cover, is that from the battery? And is it toxic?
I've had black, silver and white phones in the past. There is a saying round here that once you've had black you don't go back. Black is always going to be a classic color.. All the other colors are just fashions that come and go... Black will always be there, Look at the new iPhone 5 :-D
At first I wanted white one because it looks very beautiful and attracts a lot of attention, but when I got black one, I really liked it. It's huge screen looks even bigger on black panel, and when the phone is off it looks even more fantastic. I'd go for black second time.
I think that I would prefer white, there are not many white smartphones...
it has style, black is just a little bit to "mainstream" everyone have a black smartphone...
on the white one you can see faster dirty, but that should be no problem with the nanocoating
At first I wanted to buy white one but, then I saw the phone in real, black one looked more stylish, and the transparents looks cooler on black than on white, because too bright colors make that stripe hard to see, also screen looks better with black body. As for dirt, my friend doesnt have problems with it, just try too wash your hands before using the phone. ))
