PDA software selection is growing rapidly, as software manufacturers develop versions of popular software available to conventional PCs. Software for Palm-based PDAs is much more widely available than software for Pocket PC systems; many programs contain versions for both Palm and Pocket PC.
All PDAs are equipped with basic Personal Information Management (PIM) software, which allows you to maintain a calendar, store contacts, make to-do lists, and so on.
Gaming, photo editing, MP3 playing, and reference software is typically not included; reference software, especially dictionary sof, is also a popular extra. Anti-virus software is a good investment, especially if your PDA is equipped to access the internet via Wi-Fi wireless technology.
