One thing not covered on the Tom Bihn YouTube channel (and I haven't really seen it anywhere else either) is a demo video or videos of the Tom Bihn Brain Bag backpack. Maverick put up a some great demos of the Synapse and Smart Alec, but there is no similar demo for the Brain Bag.

It would be interesting to see how Brain Bag owners use their backpack as a daypack, and well as using it for a carry-on travel bag. It would be especially interesting to see how people use the o-rings in their brain bags to carry organized accessories.
