I've decided on white too.
Initially was going to go for black, but after seeing the pictures on Engadget, defo going for white.
Not only is white iconic Apple, but it just looks so much more fresher.
Black does look sleek, but put next to a 3GS looks too similar for me.
The white feels newer for me... if that makes sense.
Also, why do people keep saying that white will get dirty??!!
The phone is sandwiched in glass so the white plastic will not get stained or scuff marks? Any on the glass itself I'm sure can easily be cleaned.
white shows dirt more. White cars. white macbooks, white pants, white shirts, my old white guitar looked dirty all the time.
