That's a figure of speech, of course, because Open Office is the FREE alternative to Microsoft Office. I've been toying with it in Ubuntu on my XO laptop, and then installed it on my Mac G5 once I realized that X11 (the interface for Linux apps) came pre-installed on OSX 10.5. I like that O.O. opens .doc and excel files, so I've been trying to migrate all my office tasks onto Open Office.
But two factors that I discovered today sold me ultimately on it, despite some conversion troubles.*
