Carbon Copy Cloner and Netrestore

OpenOffice


openoffice.org
Mac OSX, Windows, Linux
The open source alternative to Microsoft's Office suite of programs.  I have been using the software for a couple years, and have been amazed how quickly it has matured. Open Office can read/write the common Microsoft formats (.doc, .ppt, .xls), and has the useful ability to save slide shows as flash movies.  Unfortunately it is not an OSX native program and must be run inside the the X11 window system.  I recommend NeoOffice for the OSX folks.
