leem, i have the small red DS and just bought the white and LOVE it, carry it everyday to work (and i'm always out in the field, so i carry it on the shoulders all day) and its stuffed FULL. people have said it is heavy (but that might be b/c of all the contents), but for me i dont really notice it.
As for scratches, i am not careful at all and throw it around in and out of the car, i let the metal chains hit the large CC on the front and still not one scratch. Even i'm surprised.
Very functional and GORGEOUS.
