I am just the opposite. I didn't mind a white phone*, but I want black on the front of the iPad since it doesn't distract from the screen. It is the same reason I don't want a TV with a white bezel or a computer display with a white bezel.Every iPhone and ipad I've ever owned was black or gray. I've had them all. Wouldn't think of ever getting white.
When I got my first Air,I accidentally picked up the silver with white face. I wanted black, but didn't feel like dealing with returning it so I kept it.
Now, I love being able to see the white ipad when its dark in the room and my ipad is sitting somewhere in that room. It just stands out better visually in the dark, without turning on a light.
Ended up getting a white and silver air 2. Grown accustomed to it. Very clean.
But to be honest I'd never get a white iPhone. My ipad rarely leaves the house.
*With the phones getting bigger (I have a 6 plus), I don't think I would want white for those anymore, either. Personally, I would prefer the Gold and Silver if they had the option of black on the front.
