You seriously don't need Office Ultimate, unless you're in a big Sharepoint / Office Server enviroment. Office Professional get you all the core apps, and a few goodies.
If you haven't tried it, the new Ribbon UI of Office (specifically in Word, Excel and a few others), while taking a few days to learn, absolutly smokes OO, Office 2003 and anything else you might name.
Although I haven't tried OO on Vista, I have installed the latest on an XP box. It's serviceable, mostly ok (unless you have lost of VBA macros), but decidedly old-hat compared to the sleekness of Office 2007.
Disclaimer: I have, use and recommend Office 2007 Professional to my family.
