I have returned mine and am awaiting a black one.
I bought the white originally as I always go for black and thought I would try something a little different.
Something that I hadn't banked on was the difference in materials and the in-hand feel of the device.
It has a glossy plastic bezel/surround that IMO feels very cheap. It picked up fingerprints like mad and in the week I had it, even a scratch or two.
Hard plastic back gives a cheaper feel to the whole device and is nothing like the soft-touch feel of my N7.
I was playing with the black device in-store, a week after getting the white and that was the clincher.
I recommend that anyone undecided has a play with them both first.
