Hi,
I am really thinking about buying a Z10 when it will be available in France. In my point of view the white one gives the impression of being more thinner, more sexy, so for now I'm more interested in this one.

But I've heard that the withe back isn't as soft, as good as the one of the black... Does anyone knows more about it ? Is the difference really annoying ?
Which one would you recommend me ?
Thank you for your answers and sorry for my bad english.
