I agree with the physical act of smoking being a hard habit to break. I drive a lot for work; two hours on the road at a time and what would I rather have in my hand (besides a cigarette): an e-cig, or my cellphone...have you ever just held a cigarette in your hand, just for having it there? Fragile little suckers, aren't they? In many ways your device will be a lot more durable. You can pick it up, clutch desperately at it, and put it back down again without snapping it in half.
