What's the point of the rotary control? How am I supossed to put it in my backpack with my laptops and books? It will end up breaking.

For some reason I expect it to be retractable, but I'm not sure if I'm imagining features. I'm also worried if it will break when a moron (i.e. me) is filling the backpack in a random order and quickly.
