As to your other point, is there another weapon more efficient for robbing someone? A gun only requires one hand, leaving your other hand free to hold on to what you're taking. It is immediately recognizable. It leaves little doubt as to the intent of the person holding it.
Can't argue with you there cobber, using a gun is definitely the smart way to go about nicking a Kindle.
