Black.

I have the aluminum and black Macbook, a black iPhone 5, and a white iPad 2 and the iPad is the ugliest of the bunch IMO.

White, its cuter for girls. I have a black iphone now and no matter what case I put on it, it still looks basic.

Black all the way

I didn't realise that Samsung actually went all out in the colours, they are like the first company to change the colour of the screen as well aha. Sorry

The color really depends on whatever I'm purchasing and how it looks.

ive only ever had black phones so

White is a NO-NO for me.

White iPhone, black Macbook.

Depends on the device. White phones, Black laptops > Black phones, White laptops.

I've never had black or white device in a long time. My laptop is brown. Smartphones are cyan and lime green Nokias, and a purple Xperia Z1. I used to have a white SGS3 though. I love colored devices.

Black. They show wear & tear as well as dirt less.

The White ones you can see the dirt on

It depends on the device (apple tends to look great in white) but I generally prefer black.

My computer and phone are both black (the white note 3 looks horrible imo) and my ipod is green

Blue, if not avaible, then black with a blue cover/case.
