PlusOffice for Mac
OpenZone has announced PlusOffice for the Mac, a program that offers the same functionality as the OpenOffice.org web-based applications. Features offered include a spreadsheet, text, and mathematical-formula editor, as well as a graphic program and multimedia presentation application. Users also have access to a data base creator and editor program. PlusOffice allows the import and export of PDF files, and the possibility to view or edit documents in MS Office formats such as doc, xls, and ppt.
Found on the company's website, the Mac version comes with technical support and upgrades.
