The usability is about the same as Office...

Not according to real-world users.

Office 2003 vs OpenOffice.org

"In any case, all testers liked Office 2003 and said staying with Office would likely provide the smoothest upgrade path. "It'll be easier to introduce Microsoft Office 2003 to users here at FN Manufacturing than OpenOffice because it's a lot more user-friendly than OpenOffice," said Joan Curfman, business systems supervisor at FN Manufacturing. "Training will definitely be more detailed and will take a lot longer on OpenOffice.org because the interface isn't that friendly. Users here have problems using what we already have. They'll probably find OpenOffice.org even more difficult to use and learn."
