The $35 Spider Memory Card Organizer is perilously close to the label of "fanny pack", but serves a very useful set of organizational tasks. It has space for keeping 6 CF cards and 9 SD cards, all of which are individually separated from one another. But it also has a slot for your business cards, one for your phone (which is close enough to your body that you'll actually feel it when it vibrates), and has an extra front pocket that you can get into without unzipping. And thanks to the "shelf" design, you can open the organizer one-handed, and not worry about it flopping all over the place. And, let's face it, sartorial dignity went out the window as soon as you got into photography.
