Abstract: An attachment device for use with a personal digital assistant (PDA) is provided which generally comprises a back surface, a base, and at least one securement arm. The securement arm(s) are resiliently deflectable to receive and retain the personal digital assistant under the force created in the deflection of the arms, and which allows the PDA to be selectively removed. The attachment device may include attachment apertures to secure the attachment device to a folio or other type of notebook, or to a surface such as a wall, an automobile visor, or an automobile dashboard. The attachment device may also be incorporated into a folio or similar device to provide protection to the personal digital assistant while allowing full access to, and operation of, the PDA.
