The Open Palmtop Integrated Environment is a 'fork' of the [WWW]Qtopia environment developed by [WWW]Trolltech. Opie is a completely Open Source based graphical user environment for PDAs and other devices running Linux. It is maintained by a group of people scattered around the world who are convinced of the Open Source philosophy. Opie has greatly extended and improved usability of Qtopia to become the most sophisticated free and open graphical user interface for Linux based embedded devices and PDAs. Opie features a sophisticated personal information management (PIM) framework as well as several other productivity applications. It also has extended multimedia capabilities, document model, networking and communication tools as well as support for more than a dozen languages. Based on common industry standards like XML, OBEX, IrDa et. al., Opie is capable of interacting with various devices ranging from cell phones to server backends. Opie is highly optimized for mobile devices and attempts to support the user with shortcuts and ease of use.
