The "Office Suite" is sold as Office XP. Every help/about menu of all the apps within Office lists it as Office 2002. A rare disonnect between marketing and design. You would almost think the code was ready to release and then marketing decided to change the name to match the newly released OS. Astonishing.

MS Outlook XP/2002 (now considered a member of the Office suite) has yet a third name, Outlook 10. I don't think any of the other apps are also using the 10 suffix though. Probably a good thing. Mocking them is already too easy.
