The free office suite LibreOffice actually still supports both Tiger and PowerPC. The app performs quite decently on my old Mac mini G4 and even on my ancient Power Mac G4 (466Mhz). It runs a lot better than Office 2008 or iWork, although Office 2004 remains the fastest. Still, it seems like a solid application, though few people use it. Is anybody else using this application on the PowerPC? What are your experiences with it? I kind of like the idea of having one office suite on all my systems.
