We need to migrate an Excel/Access application from Office 2003 to Office 2007. Thus, I'm considering the purchase of laptop with Vista (64-bit) and Office 2007. I believe all users will remain on XP (32-bit) for a while longer but many will move to Office 2007.

Might there be any issues from me developing with VISTA but user running XP? Asked differently, does the operating system impact development if the software running the app is the same? (We'd all be running Office 2007 but different versions of Windows.)

I've considered installing both Office 2003 and 2007 on my existing XP laptop but read some posts about resulting issues so I'd like to have each version of Office on a separate station.

Thoughts???
