The theme functionality was noticable throughout the apps (even Visio if I remember correctly) although I didn’t spot it in Outlook. The big difference for me wasn’t Powerpoint but Excel – the charts it produced were great and it was very easy to change the look and feel of a series of charts while keeping them all consistent – something that wasn’t easy to do in previous versions.

I’ve updated the post to link to my Flickr set of screenshots.
