and open source software, including web and FTP servers, databases, and compilers. Developers have created several replacement Linux distributions for the Zaurus. Software provided by Sharp includes basic PDA packages such as a datebook, addressbook, and to do list. These PIM applications are fairly unsophisticated, and a number of individuals and groups have developed alternatives. One popular - and free - alternative that runs on the Sharp ROM and OpenZaurus as well as Windows and Linux is the KDE PIM/Platform-independent set of applications. KDE PIM/PI is based on PIM applications from the KDE desktop suite for Linux. KDE PIM/PI includes KOrganizer/Platform-independent (or KOPI), KAddressbook/Platform-independent (or KAPI), K-OpieMail/pi (or OMPI), K-Phone/pi (kppi) and PwM/PI, a password manager with strong encryption. In addition to standard PDA applications there are many programs available that are more commonly associated with desktop and laptop computers. Among these are a selection of office programs, web browsers, media applications and many others.
