I really wanted the white one but I went with the black one. I think my eye and the whole perceived contrast thingy would make me in the end wish I had ordered black if I had ordered white.
I just like how things pop and contrast against a dark background so I went with the black one. Plus I thought maybe in a year's time the resale value would be better for black as it would appeal to more men buyers than white would. I sold my Ipad 1 in order to purchase my Ipad 2. Still retained great resale value and I just sold it last week. 16gig wifi only for $425..
