To put this into the right perspective - I am a very peculiar user of word processing applications. I spend most of my time with writing or reviewing documents. That is, the feature areas I care about most are revision tracking and commenting.
To illustrate my point, I took the following screenshot of Word:
This is a rather orderly document, with one comment tacked to a section of a sentence, plus I added "stuff" (a pointless edit). During the lifetime of this document, more comments will be added, as well as edits by multiple people.
So what do I do once all comments are in? Yep, accept or reject the changes. If I am fine with the changes, I mark that block containing all the changes, and go to the toolbar to accept the changes:
That's how it works in Microsoft Word. Now let's take a look at OpenOffice.org Writer:
I couldn't care less about the missing toolbar to access the reviewing functionality directly, however, I do care deeply about the internal workings:
That might be practical for a small document, but definitely not for one that was reviewed by 5+ people and contains 100+ changes (which, funny enough, does happen a lot for specification documents or book chapters...).
Without a proper editing workflow, OOo is not going to play a major part in my everyday work process any time soon.
