'Ballistic Nylon' just rolls off the tongue so nicely, and makes even the simplest of objects appear exotic. Take for example the bags we use to carry around cables, power adapters, and things of this nature. Sure, they could be packed away in a Ziplock bag, but what fun would that be?
To be realistic, most people don't pay all that much attention to the bags we use to lug around a adapter cables, ac/adaptors or for that matter even a digital camera or notebook. Most of the time we simply use whichever carry case was thrown in with the equipment when we bought it - typically made from vinyl, nylon or pleather, and without much credence towards appearance, comfort or long term durability and protection of the gear inside. There are of course cases which are built like a tank, and do a great job, but in my experience they are few and far between.
