Very cool new download from the OfficeLabs team - Canvas for OneNote. This allows you to do something I’ve always struggled with in OneNote – that is visualise all of content in a Seadragon style.
The video explains it better than I ever could and you can download for free now.
Also impressed with the pptPlex application; really opens up flexibility of PowerPoint - http://www.deburca.co.uk/blog/tabid/57/EntryID/190/Default.aspx
