A computer with its vast memory capability in the form of a PDA that can easily store and give information at a click of button. This process is hence more appealing to a trainee, a nurse or a clinician. This is one reason for their popularity in this field that is so information intensive and complex. The PDA has now found a place in the pocket of the white-coat, the appeal is even more since it is lightweight, small, easy to carry around, it does not interfere with the various medical equipments functioning and it can talk to the desktop computer with ease.
