Agreed - it's really easy to set these options in OpenOffice (I don't know why they aren't the default - that would be make the software "Just Work" the way users would expect).

But I'd be surprised if 95% of users in any organisations really are happy with OpenOffice. I used it exclusively for over a year, and it's horrible. Yes, technically it does the job. But it was very slow to load, opening files from a network share was particularly bad. I am so much happier with MS Office. I would prefer Office 97 or 200 to OpenOffice. There is little development going into OOo any more either, so it's not likely to get much better.

There are some alternatives that look ok. I tried Softmaker Office a while back and that was great.
