A portable organizer which includes a foldable case having an interior compartment is disclosed. The case may have a zipper along its periphery. Located within the compartment are various holders for securing a wide variety of personal organizational items such as business cards, notepads, an identification card, etc. Also located within the compartment is an adjustable clamp which may be used to grip a personal data assistant device. The clamp includes an upper bracket, a lower bracket, and an elastic member attached to the brackets. The lower bracket may be secured to the case. The upper bracket should not be attached to the case. Covering the elastic member is a piece of material sewn or otherwise attached to the case. The cover acts as a guide in order to maintain the clamp in place. A personal data assistant, such as a miniature electronic device or PALM PILOT may be gripped by the clamp by extending the upper bracket upwardly so that the device may rest on the lower bracket and against the covering member. The upper bracket is then released so that the upper bracket grips the device and holds it in place. Rubber or foam pads may be placed on the upper and lower brackets where the device contacts the brackets so that the device is not scratched or otherwise damaged by the brackets.
