I know this isn't Web 2.0, but I'm not sure who to ask other than this lovely group... I'm putting together a resource CD/DVD and one of the contributors has recorded an audio PPT presentation in PowerPoint 2007. It can be viewed with the PowerPoint viewer 2007 but not the PowerPoint viewer 2003. I'm concerned that people will not have the PowerPoint 2007 viewer if they are still using Office 2003.
So my question is: are education institutions using Office 2003 or 2007?
