After using the Brain Bag for several weeks, I'm thinking a great product would be a snake charmer like module that could mount in the non laptop compartment with the extra clip hard points. This would be huge, because you could keep your most often used stuff in a separate module located near the top of the bag.
I'm envisioning replacing one of the mesh sides and bottom of the snake charmer with a foam piece to which are mounted the same mounting points as the brain cells.
Make sense?
