There is a mixed bag at my company....we have a little over 5,000 desktops/laptops and about third are running Office 2007 with Windows 7....another third are running Office 2007 with XP (I am in this group) and the final third are running Office 2003 with XP (Those are the groups that I know about. I wouldn't be surprised to find some group or other running Windows 7 and Office 2003 - that would be just like this company).

We have exclusively moved from SQL Server 2000 to SQL Server 2008 (maybe there is a God!) and we are being upgraded to SharePoint 2010.

The desktop/laptop community, however, remains a hodgepoge.
