I was a user of Office 97 for many years in the late 1990s, and then I used that along with Office 2000 for a few years - Office 2000 is definitely an improvement and has certain new features that are helpful. But in Office 2003 Microsoft decided to mess with the interface, and you couldn't revert back to the classic one (at least on XP) so I didn't adopt that version and well the versions after that are completely messed up, broken and unusable from my point of view.
So I continue using Office 2000 till this day, and I have no plans and no reason to use anything else not to mention downgrade to the newer junk that M$ has put up in the past 10 years.
Office 2000 does everything I need an office software to do, and things it does not do - I don't need. And one thing I definitely don't need is Microsoft's "support" for using a damn word processor ;-)
