With PowerPoint 2007, you will no longer find the feature available in PowerPoint 2003 and previous versions that let you compare your presentations — which was great if you received a presentation back from a colleague and he or she made changes you were not aware of. You can however place both presentations side by side and compare individual slides in PowerPoint 2007 — not too great a workaround, but it does allow you to compare the slides.
