I will be getting an Imac soon and will have Windows 7 on it via Fusion. Given that would you put office on native or on Windows 7? I am going back and forth on this. I have lots of .xls & .doc from 2003 version to bring over.
I prefer to work in OS X as much as possible so I really like having Office 2008 for Mac. I am able to handle 90-95% of tasks in OS X with Office 2008. I keep Office 2007 running in a VM for that 5-10% of the time. I'm hoping Office 2010's return to near Windows Office parity (with VBA support and Outlook client) will make Windows completely unnecessary (other than my many Windows games)!
Cheers,
