Discussed putting Office 2007 on our managed desktop last night - and agreed to do it this summer. Currently we have Office 2003 on it, but new PCs and laptops come equipped with Office 2007 and have done for a while. So many members of the University, especially students, are using Office 2007 on their own machines and are surprised when they come to University and find Office 2003 on the managed desktop. The Microsoft treadmill is not something we particularly want to be on, but in this case, it's unavoidable - we're supposed to be an innovative department, and providing out of date software hardly supports that vision!
There will be communication and training issues, but nothing insurmountable. Now, I'm just about to update my mac to Office 2008 and see what differences there are!
