Crap? Come on. They are probably a bit more difficult to use, etc, than the bloatware from Microsoft that people are addicted to like crack. But when some suit that I am not allowed to strangle sends me a "Word document", OpenOffice does a fairly decent job of letting me view it, edit it and send it back without spending so much time on it that I start feeling like a pedophile. :-)

P.S: if you have a Mac, I recommend iWork, which costs I think about 1/4th of Microsoft "crap", and is much less of an eyesore.
