Nearly every desktop computer and laptop has some kind of office or productivity suite. Many of these have several applications in them that can be used together to replace a paper office, but the most common three applications are word processors, spread sheets, and presentation creators/viewers. On Win32 machines, there are several commercial suites that reign supreme, and on Macintosh systems iWork and MS Office are common (though NeoOffice is a close 3rd). So what options are available for UNIX/Linux systems? I have found there are six common office/productivity solutions for these platforms with which most of us are already familiar.
