QuantumSTEP is a Mac/Cocoa compatible Application Platform and Application Suite (Calendar, Addressbook, Web Browser, File Manager, etc.) that turns a Sharp Zaurus into sort of a "Baby Mac".
You can even port/write programs to the Zaurus by using Xcode and Zaurus-X-gcc to recompile for the QuantumSTEP platform.QuantumSTEP is based on the GUI-Library mySTEP (which itself is based on mGStep/GNUstep) and an X11 server.
