                Handheld computers, especially personal digital assistants (PDAs), are increasingly being used throughout the Department
                of Defense. This article highlights some of the ways that PDAs are used today and are envisioned for the future. It outlines
                some of the considerations involved in a PDA procurement, discusses four tools for developing PDA resource materials – pro-
                gramming tools, hypertext markup language- and eXtensible markup language-based tools, text tools, and calendar tools –
                outlines some of the benefits and challenges associated with using PDAs, and shares several lessons learned.
