This Calvin Klein sunglasses is a great design because it features a detachable arm that reveals a 4GB USB flash drive. It is so well “concealled” in the right arm of the sunglasses and doesn’t affect its style look.

One thing I don’t understand is that why they only design to have one USB drive on the right arm of the sunglasses; why can’t they make use of the other arm for another USB drive?

Cost could be the factor but since it is Calvin Klein, I believe poeple will still buy with additional price for extra USB flash drive. By the way, 4GB is big enough for normal use.
