A few times a year, I download the latest version of star-office / open-office / libre-office and try it on a MSWord document from work. My most recent attempt was 2 weeks ago. I have yet to see a correctly-formatted result. In the beginning, simple things like bullets were wrong.

Which you had to dismiss. Every. Fucking. Time.
And somewhere deep within Redmond, someone is still wondering why MS Word DOC format didn't become a universal document interface interchange format.
