Ok, I bought the white iPhone 4s on launch day. Even though I think the white is nice looking i just got tired of the white. My wife's upgrade was a couple of weeks ago and she loves the white so I gave her mine and bought the black for me.
I am not sure what it is but I just got tired of looking at the white. I have the white iPad 2 since launch date and still love the color. Not sure why the white seems a better fit on the iPad compared to the iPhone?
